What Is a Case Study? | Definition, Examples & Methods
Published on May 8, 2019 by Shona McCombes . Revised on January 30, 2023.
A case study is a detailed study of a specific subject, such as a person, group, place, event, organization, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.
A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating and understanding different aspects of a research problem .
Table of contents
When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyze the case.
A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.
Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.
You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.
Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:
- Provide new or unexpected insights into the subject
- Challenge or complicate existing assumptions and theories
- Propose practical courses of action to resolve a problem
- Open up new directions for future research
Unlike quantitative or experimental research , a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.
However, you can also choose a more common or representative case to exemplify a particular category, experience or phenomenon.

While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:
- Exemplify a theory by showing how it explains the case under investigation
- Expand on a theory by uncovering new concepts and ideas that need to be incorporated
- Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions
To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.
There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews , observations , and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data.
The aim is to gain as thorough an understanding as possible of the case and its context.
In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.
How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis , with separate sections or chapters for the methods , results and discussion .
Others are written in a more narrative style, aiming to explore the case from various angles and analyze its meanings and implications (for example, by using textual analysis or discourse analysis ).
In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Case Study in Education Research by Lorna Hamilton LAST REVIEWED: 21 April 2021 LAST MODIFIED: 27 June 2018 DOI: 10.1093/obo/9780199756810-0201
It is important to distinguish between case study as a teaching methodology and case study as an approach, genre, or method in educational research. The use of case study as teaching method highlights the ways in which the essential qualities of the case—richness of real-world data and lived experiences—can help learners gain insights into a different world and can bring learning to life. The use of case study in this way has been around for about a hundred years or more. Case study use in educational research, meanwhile, emerged particularly strongly in the 1970s and 1980s in the United Kingdom and the United States as a means of harnessing the richness and depth of understanding of individuals, groups, and institutions; their beliefs and perceptions; their interactions; and their challenges and issues. Writers, such as Lawrence Stenhouse, advocated the use of case study as a form that teacher-researchers could use as they focused on the richness and intensity of their own practices. In addition, academic writers and postgraduate students embraced case study as a means of providing structure and depth to educational projects. However, as educational research has developed, so has debate on the quality and usefulness of case study as well as the problems surrounding the lack of generalizability when dealing with single or even multiple cases. The question of how to define and support case study work has formed the basis for innumerable books and discursive articles, starting with Robert Yin’s original book on case study ( Yin 1984 , cited under General Overview and Foundational Texts of the Late 20th Century ) to the myriad authors who attempt to bring something new to the realm of case study in educational research in the 21st century.
This section briefly considers the ways in which case study research has developed over the last forty to fifty years in educational research usage and reflects on whether the field has finally come of age, respected by creators and consumers of research. Case study has its roots in anthropological studies in which a strong ethnographic approach to the study of peoples and culture encouraged researchers to identify and investigate key individuals and groups by trying to understand the lived world of such people from their points of view. Although ethnography has emphasized the role of researcher as immersive and engaged with the lived world of participants via participant observation, evolving approaches to case study in education has been about the richness and depth of understanding that can be gained through involvement in the case by drawing on diverse perspectives and diverse forms of data collection. Embracing case study as a means of entering these lived worlds in educational research projects, was encouraged in the 1970s and 1980s by researchers, such as Lawrence Stenhouse, who provided a helpful impetus for case study work in education ( Stenhouse 1980 ). Stenhouse wrestled with the use of case study as ethnography because ethnographers traditionally had been unfamiliar with the peoples they were investigating, whereas educational researchers often worked in situations that were inherently familiar. Stenhouse also emphasized the need for evidence of rigorous processes and decisions in order to encourage robust practice and accountability to the wider field by allowing others to judge the quality of work through transparency of processes. Yin 1984 , the first book focused wholly on case study in research, gave a brief and basic outline of case study and associated practices. Various authors followed this approach, striving to engage more deeply in the significance of case study in the social sciences. Key among these are Merriam 1988 and Stake 1995 , along with Yin 1984 , who established powerful groundings for case study work. Additionally, evidence of the increasing popularity of case study can be found in a broad range of generic research methods texts, but these often do not have much scope for the extensive discussion of case study found in case study–specific books. Yin’s books and numerous editions provide a developing or evolving notion of case study with more detailed accounts of the possible purposes of case study, followed by Merriam 1988 and Stake 1995 who wrestled with alternative ways of looking at purposes and the positioning of case study within potential disciplinary modes. The authors referenced in this section are often characterized as the foundational authors on this subject and may have published various editions of their work, cited elsewhere in this article, based on their shifting ideas or emphases.
Merriam, S. B. 1988. Case study research in education: A qualitative approach . San Francisco: Jossey-Bass.
Save Citation » Export Citation » Share Citation »
This is Merriam’s initial text on case study and is eminently accessible. The author establishes and reinforces various key features of case study; demonstrates support for positioning the case within a subject domain, e.g., psychology, sociology, etc.; and further shapes the case according to its purpose or intent.
Stake, R. E. 1995. The art of case study research . Thousand Oaks, CA: SAGE.
Stake is a very readable author, accessible and yet engaging with complex topics. The author establishes his key forms of case study: intrinsic, instrumental, and collective. Stake brings the reader through the process of conceptualizing the case, carrying it out, and analyzing the data. The author uses authentic examples to help readers understand and appreciate the nuances of an interpretive approach to case study.

A key article in which Stenhouse sets out his stand on case study work. Those interested in the evolution of case study use in educational research should consider this article and the insights given.
Yin, R. K. 1984. Case Study Research: Design and Methods . Beverley Hills, CA: SAGE.
This preliminary text from Yin was very basic. However, it may be of interest in comparison with later books because Yin shows the ways in which case study as an approach or method in research has evolved in relation to detailed discussions of purpose, as well as the practicalities of working through the research process.

Benefits and Limitations
Types of case studies, how to write a case study.
A case study is an in-depth study of one person, group, or event. In a case study, nearly every aspect of the subject's life and history is analyzed to seek patterns and causes of behavior. Case studies can be used in various fields, including psychology, medicine, education, anthropology, political science, and social work.
The purpose of a case study is to learn as much as possible about an individual or group so that the information can be generalized to many others. Unfortunately, case studies tend to be highly subjective, and it is sometimes difficult to generalize results to a larger population.
While case studies focus on a single individual or group, they follow a format similar to other types of psychology writing. If you are writing a case study, it is important to follow the rules of APA format .
A case study can have both strengths and weaknesses. Researchers must consider these pros and cons before deciding if this type of study is appropriate for their needs.
One of the greatest advantages of a case study is that it allows researchers to investigate things that are often difficult to impossible to replicate in a lab. Some other benefits of a case study:
- Allows researchers to collect a great deal of information
- Give researchers the chance to collect information on rare or unusual cases
- Permits researchers to develop hypotheses that can be explored in experimental research
On the negative side, a case study:
- Cannot necessarily be generalized to the larger population
- Cannot demonstrate cause and effect
- May not be scientifically rigorous
- Can lead to bias
Researchers may choose to perform a case study if they are interested in exploring a unique or recently discovered phenomenon. The insights gained from such research can help the researchers develop additional ideas and study questions that might be explored in future studies.
However, it is important to remember that the insights gained from case studies cannot be used to determine cause and effect relationships between variables. However, case studies may be used to develop hypotheses that can then be addressed in experimental research.
Case Study Examples
There have been a number of notable case studies in the history of psychology. Much of Freud's work and theories were developed through the use of individual case studies. Some great examples of case studies in psychology include:
- Anna O : Anna O. was a pseudonym of a woman named Bertha Pappenheim, a patient of a physician named Josef Breuer. While she was never a patient of Freud's, Freud and Breuer discussed her case extensively. The woman was experiencing symptoms of a condition that was then known as hysteria and found that talking about her problems helped relieve her symptoms. Her case played an important part in the development of talk therapy as an approach to mental health treatment.
- Phineas Gage : Phineas Gage was a railroad employee who experienced a terrible accident in which an explosion sent a metal rod through his skull, damaging important portions of his brain. Gage recovered from his accident but was left with serious changes in both personality and behavior.
- Genie : Genie was a young girl subjected to horrific abuse and isolation. The case study of Genie allowed researchers to study whether language could be taught even after critical periods for language development had been missed. Her case also served as an example of how scientific research may interfere with treatment and lead to further abuse of vulnerable individuals.
Such cases demonstrate how case research can be used to study things that researchers could not replicate in experimental settings. In Genie's case, her horrific abuse had denied her the opportunity to learn language at critical points in her development.
This is clearly not something that researchers could ethically replicate, but conducting a case study on Genie allowed researchers the chance to study phenomena that are otherwise impossible to reproduce.
There are a few different types of case studies that psychologists and other researchers might utilize:
- Collective case studies : These involve studying a group of individuals. Researchers might study a group of people in a certain setting or look at an entire community. For example, psychologists might explore how access to resources in a community has affected the collective mental well-being of those living there.
- Descriptive case studies : These involve starting with a descriptive theory. The subjects are then observed, and the information gathered is compared to the pre-existing theory.
- Explanatory case studies : These are often used to do causal investigations. In other words, researchers are interested in looking at factors that may have caused certain things to occur.
- Exploratory case studies : These are sometimes used as a prelude to further, more in-depth research. This allows researchers to gather more information before developing their research questions and hypotheses .
- Instrumental case studies : These occur when the individual or group allows researchers to understand more than what is initially obvious to observers.
- Intrinsic case studies : This type of case study is when the researcher has a personal interest in the case. Jean Piaget's observations of his own children are good examples of how an intrinsic cast study can contribute to the development of a psychological theory.
The three main case study types often used are intrinsic, instrumental, and collective. Intrinsic case studies are useful for learning about unique cases. Instrumental case studies help look at an individual to learn more about a broader issue. A collective case study can be useful for looking at several cases simultaneously.
The type of case study that psychology researchers utilize depends on the unique characteristics of the situation as well as the case itself.
There are also different methods that can be used to conduct a case study, including prospective and retrospective case study methods.
Prospective case study methods are those in which an individual or group of people is observed in order to determine outcomes. For example, a group of individuals might be watched over an extended period of time to observe the progression of a particular disease.
Retrospective case study methods involve looking at historical information. For example, researchers might start with an outcome, such as a disease, and then work their way backward to look at information about the individual's life to determine risk factors that may have contributed to the onset of the illness.
Where to Find Data
There are a number of different sources and methods that researchers can use to gather information about an individual or group. Six major sources that have been identified by researchers are:
- Archival records : Census records, survey records, and name lists are examples of archival records.
- Direct observation : This strategy involves observing the subject, often in a natural setting . While an individual observer is sometimes used, it is more common to utilize a group of observers.
- Documents : Letters, newspaper articles, administrative records, etc., are the types of documents often used as sources.
- Interviews : Interviews are one of the most important methods for gathering information in case studies. An interview can involve structured survey questions or more open-ended questions.
- Participant observation : When the researcher serves as a participant in events and observes the actions and outcomes, it is called participant observation.
- Physical artifacts : Tools, objects, instruments, and other artifacts are often observed during a direct observation of the subject.
Section 1: A Case History
This section will have the following structure and content:
Background information : The first section of your paper will present your client's background. Include factors such as age, gender, work, health status, family mental health history, family and social relationships, drug and alcohol history, life difficulties, goals, and coping skills and weaknesses.
Description of the presenting problem : In the next section of your case study, you will describe the problem or symptoms that the client presented with.
Describe any physical, emotional, or sensory symptoms reported by the client. Thoughts, feelings, and perceptions related to the symptoms should also be noted. Any screening or diagnostic assessments that are used should also be described in detail and all scores reported.
Your diagnosis : Provide your diagnosis and give the appropriate Diagnostic and Statistical Manual code. Explain how you reached your diagnosis, how the client's symptoms fit the diagnostic criteria for the disorder(s), or any possible difficulties in reaching a diagnosis.
Section 2: Treatment Plan
This portion of the paper will address the chosen treatment for the condition. This might also include the theoretical basis for the chosen treatment or any other evidence that might exist to support why this approach was chosen.
- Cognitive behavioral approach : Explain how a cognitive behavioral therapist would approach treatment. Offer background information on cognitive behavioral therapy and describe the treatment sessions, client response, and outcome of this type of treatment. Make note of any difficulties or successes encountered by your client during treatment.
- Humanistic approach : Describe a humanistic approach that could be used to treat your client, such as client-centered therapy . Provide information on the type of treatment you chose, the client's reaction to the treatment, and the end result of this approach. Explain why the treatment was successful or unsuccessful.
- Psychoanalytic approach : Describe how a psychoanalytic therapist would view the client's problem. Provide some background on the psychoanalytic approach and cite relevant references. Explain how psychoanalytic therapy would be used to treat the client, how the client would respond to therapy, and the effectiveness of this treatment approach.
- Pharmacological approach : If treatment primarily involves the use of medications, explain which medications were used and why. Provide background on the effectiveness of these medications and how monotherapy may compare with an approach that combines medications with therapy or other treatments.
This section of a case study should also include information about the treatment goals, process, and outcomes.
When you are writing a case study, you should also include a section where you discuss the case study itself, including the strengths and limitiations of the study. You should note how the findings of your case study might support previous research.
In your discussion section, you should also describe some of the implications of your case study. What ideas or findings might require further exploration? How might researchers go about exploring some of these questions in additional studies?
Here are a few additional pointers to keep in mind when formatting your case study:
- Never refer to the subject of your case study as "the client." Instead, their name or a pseudonym.
- Read examples of case studies to gain an idea about the style and format.
- Remember to use APA format when citing references .
A Word From Verywell
Case studies can be a useful research tool, but they need to be used wisely. In many cases, they are best utilized in situations where conducting an experiment would be difficult or impossible. They are helpful for looking at unique situations and allow researchers to gather a great deal of information about a specific individual or group of people.
If you have been directed to write a case study for a psychology course, be sure to check with your instructor for any specific guidelines that you are required to follow. If you are writing your case study for professional publication, be sure to check with the publisher for their specific guidelines for submitting a case study.

- Case Reports
An article that describes and interprets an individual case, often written in the form of a detailed story. Case reports often describe:
- Unique cases that cannot be explained by known diseases or syndromes
- Cases that show an important variation of a disease or condition
- Cases that show unexpected events that may yield new or useful information
- Cases in which one patient has two or more unexpected diseases or disorders
Case reports are considered the lowest level of evidence, but they are also the first line of evidence, because they are where new issues and ideas emerge. This is why they form the base of our pyramid. A good case report will be clear about the importance of the observation being reported.
If multiple case reports show something similar, the next step might be a case-control study to determine if there is a relationship between the relevant variables.
- Can help in the identification of new trends or diseases
- Can help detect new drug side effects and potential uses (adverse or beneficial)
- Educational – a way of sharing lessons learned
- Identifies rare manifestations of a disease
Disadvantages
- Cases may not be generalizable
- Not based on systematic studies
- Causes or associations may have other explanations
- Can be seen as emphasizing the bizarre or focusing on misleading elements
Design pitfalls to look out for
The patient should be described in detail, allowing others to identify patients with similar characteristics.
Does the case report provide information about the patient's age, sex, ethnicity, race, employment status, social situation, medical history, diagnosis, prognosis, previous treatments, past and current diagnostic test results, medications, psychological tests, clinical and functional assessments, and current intervention?
Case reports should include carefully recorded, unbiased observations.
Does the case report include measurements and/or recorded observations of the case? Does it show a bias?
Case reports should explore and infer, not confirm, deduce, or prove. They cannot demonstrate causality or argue for the adoption of a new treatment approach.
Does the case report present a hypothesis that can be confirmed by another type of study?
Fictitious Example
A physician treated a young and otherwise healthy patient who came to her office reporting numbness all over her body. The physician could not determine any reason for this numbness and had never seen anything like it. After taking an extensive history the physician discovered that the patient had recently been to the beach for a vacation and had used a very new type of spray sunscreen. The patient had stored the sunscreen in her cooler at the beach because she liked the feel of the cool spray in the hot sun. The physician suspected that the spray sunscreen had undergone a chemical reaction from the coldness which caused the numbness. She also suspected that because this is a new type of sunscreen other physicians may soon be seeing patients with this numbness.
The physician wrote up a case report describing how the numbness presented, how and why she concluded it was the spray sunscreen, and how she treated the patient. Later, when other doctors began seeing patients with this numbness, they found this case report helpful as a starting point in treating their patients.

This case report was published by eight physicians in New York city who had unexpectedly seen eight male patients with Kaposi’s sarcoma (KS). Prior to this, KS was very rare in the U.S. and occurred primarily in the lower extremities of older patients. These cases were decades younger, had generalized KS, and a much lower rate of survival. This was before the discovery of HIV or the use of the term AIDS and this case report was one of the first published items about AIDS patients.

What is it?
Case study is a research methodology, typically seen in social and life sciences. There is no one definition of case study research. 1 However, very simply… ‘a case study can be defined as an intensive study about a person, a group of people or a unit, which is aimed to generalize over several units’. 1 A case study has also been described as an intensive, systematic investigation of a single individual, group, community or some other unit in which the researcher examines in-depth data relating to several variables. 2
Often there are several similar cases to consider such as educational or social service programmes that are delivered from a number of locations. Although similar, they are complex and have unique features. In these circumstances, the evaluation of several, similar cases will provide a better answer to a research question than if only one case is examined, hence the multiple-case study. Stake asserts that the cases are grouped and viewed as one entity, called the quintain . 6 ‘We study what is similar and different about the cases to understand the quintain better’. 6
The steps when using case study methodology are the same as for other types of research. 6 The first step is defining the single case or identifying a group of similar cases that can then be incorporated into a multiple-case study. A search to determine what is known about the case(s) is typically conducted. This may include a review of the literature, grey literature, media, reports and more, which serves to establish a basic understanding of the cases and informs the development of research questions. Data in case studies are often, but not exclusively, qualitative in nature. In multiple-case studies, analysis within cases and across cases is conducted. Themes arise from the analyses and assertions about the cases as a whole, or the quintain, emerge. 6
Benefits and limitations of case studies
If a researcher wants to study a specific phenomenon arising from a particular entity, then a single-case study is warranted and will allow for a in-depth understanding of the single phenomenon and, as discussed above, would involve collecting several different types of data. This is illustrated in example 1 below.
Using a multiple-case research study allows for a more in-depth understanding of the cases as a unit, through comparison of similarities and differences of the individual cases embedded within the quintain. Evidence arising from multiple-case studies is often stronger and more reliable than from single-case research. Multiple-case studies allow for more comprehensive exploration of research questions and theory development. 6
Despite the advantages of case studies, there are limitations. The sheer volume of data is difficult to organise and data analysis and integration strategies need to be carefully thought through. There is also sometimes a temptation to veer away from the research focus. 2 Reporting of findings from multiple-case research studies is also challenging at times, 1 particularly in relation to the word limits for some journal papers.
Examples of case studies
Example 1: nurses’ paediatric pain management practices.
One of the authors of this paper (AT) has used a case study approach to explore nurses’ paediatric pain management practices. This involved collecting several datasets:
Observational data to gain a picture about actual pain management practices.
Questionnaire data about nurses’ knowledge about paediatric pain management practices and how well they felt they managed pain in children.
Questionnaire data about how critical nurses perceived pain management tasks to be.
These datasets were analysed separately and then compared 7–9 and demonstrated that nurses’ level of theoretical did not impact on the quality of their pain management practices. 7 Nor did individual nurse’s perceptions of how critical a task was effect the likelihood of them carrying out this task in practice. 8 There was also a difference in self-reported and observed practices 9 ; actual (observed) practices did not confirm to best practice guidelines, whereas self-reported practices tended to.
Example 2: quality of care for complex patients at Nurse Practitioner-Led Clinics (NPLCs)
The other author of this paper (RH) has conducted a multiple-case study to determine the quality of care for patients with complex clinical presentations in NPLCs in Ontario, Canada. 10 Five NPLCs served as individual cases that, together, represented the quatrain. Three types of data were collected including:
Review of documentation related to the NPLC model (media, annual reports, research articles, grey literature and regulatory legislation).
Interviews with nurse practitioners (NPs) practising at the five NPLCs to determine their perceptions of the impact of the NPLC model on the quality of care provided to patients with multimorbidity.
Chart audits conducted at the five NPLCs to determine the extent to which evidence-based guidelines were followed for patients with diabetes and at least one other chronic condition.
The three sources of data collected from the five NPLCs were analysed and themes arose related to the quality of care for complex patients at NPLCs. The multiple-case study confirmed that nurse practitioners are the primary care providers at the NPLCs, and this positively impacts the quality of care for patients with multimorbidity. Healthcare policy, such as lack of an increase in salary for NPs for 10 years, has resulted in issues in recruitment and retention of NPs at NPLCs. This, along with insufficient resources in the communities where NPLCs are located and high patient vulnerability at NPLCs, have a negative impact on the quality of care. 10
These examples illustrate how collecting data about a single case or multiple cases helps us to better understand the phenomenon in question. Case study methodology serves to provide a framework for evaluation and analysis of complex issues. It shines a light on the holistic nature of nursing practice and offers a perspective that informs improved patient care.

Case-based learning.
Case-based learning (CBL) is an established approach used across disciplines where students apply their knowledge to real-world scenarios, promoting higher levels of cognition (see Bloom’s Taxonomy ). In CBL classrooms, students typically work in groups on case studies, stories involving one or more characters and/or scenarios. The cases present a disciplinary problem or problems for which students devise solutions under the guidance of the instructor. CBL has a strong history of successful implementation in medical, law, and business schools, and is increasingly used within undergraduate education, particularly within pre-professional majors and the sciences (Herreid, 1994). This method involves guided inquiry and is grounded in constructivism whereby students form new meanings by interacting with their knowledge and the environment (Lee, 2012).
There are a number of benefits to using CBL in the classroom. In a review of the literature, Williams (2005) describes how CBL: utilizes collaborative learning, facilitates the integration of learning, develops students’ intrinsic and extrinsic motivation to learn, encourages learner self-reflection and critical reflection, allows for scientific inquiry, integrates knowledge and practice, and supports the development of a variety of learning skills.
CBL has several defining characteristics, including versatility, storytelling power, and efficient self-guided learning. In a systematic analysis of 104 articles in health professions education, CBL was found to be utilized in courses with less than 50 to over 1000 students (Thistlethwaite et al., 2012). In these classrooms, group sizes ranged from 1 to 30, with most consisting of 2 to 15 students. Instructors varied in the proportion of time they implemented CBL in the classroom, ranging from one case spanning two hours of classroom time, to year-long case-based courses. These findings demonstrate that instructors use CBL in a variety of ways in their classrooms.
The stories that comprise the framework of case studies are also a key component to CBL’s effectiveness. Jonassen and Hernandez-Serrano (2002, p.66) describe how storytelling:
Is a method of negotiating and renegotiating meanings that allows us to enter into other’s realms of meaning through messages they utter in their stories,
Helps us find our place in a culture,
Allows us to explicate and to interpret, and
Facilitates the attainment of vicarious experience by helping us to distinguish the positive models to emulate from the negative model.
Neurochemically, listening to stories can activate oxytocin, a hormone that increases one’s sensitivity to social cues, resulting in more empathy, generosity, compassion and trustworthiness (Zak, 2013; Kosfeld et al., 2005). The stories within case studies serve as a means by which learners form new understandings through characters and/or scenarios.
CBL is often described in conjunction or in comparison with problem-based learning (PBL). While the lines are often confusingly blurred within the literature, in the most conservative of definitions, the features distinguishing the two approaches include that PBL involves open rather than guided inquiry, is less structured, and the instructor plays a more passive role. In PBL multiple solutions to the problem may exit, but the problem is often initially not well-defined. PBL also has a stronger emphasis on developing self-directed learning. The choice between implementing CBL versus PBL is highly dependent on the goals and context of the instruction. For example, in a comparison of PBL and CBL approaches during a curricular shift at two medical schools, students and faculty preferred CBL to PBL (Srinivasan et al., 2007). Students perceived CBL to be a more efficient process and more clinically applicable. However, in another context, PBL might be the favored approach.
In a review of the effectiveness of CBL in health profession education, Thistlethwaite et al. (2012), found several benefits:
Students enjoyed the method and thought it enhanced their learning,
Instructors liked how CBL engaged students in learning,
CBL seemed to facilitate small group learning, but the authors could not distinguish between whether it was the case itself or the small group learning that occurred as facilitated by the case.
Other studies have also reported on the effectiveness of CBL in achieving learning outcomes (Bonney, 2015; Breslin, 2008; Herreid, 2013; Krain, 2016). These findings suggest that CBL is a vehicle of engagement for instruction, and facilitates an environment whereby students can construct knowledge.
Science – Students are given a scenario to which they apply their basic science knowledge and problem-solving skills to help them solve the case. One example within the biological sciences is two brothers who have a family history of a genetic illness. They each have mutations within a particular sequence in their DNA. Students work through the case and draw conclusions about the biological impacts of these mutations using basic science. Sample cases: You are Not the Mother of Your Children ; Organic Chemisty and Your Cellphone: Organic Light-Emitting Diodes ; A Light on Physics: F-Number and Exposure Time
Medicine – Medical or pre-health students read about a patient presenting with specific symptoms. Students decide which questions are important to ask the patient in their medical history, how long they have experienced such symptoms, etc. The case unfolds and students use clinical reasoning, propose relevant tests, develop a differential diagnoses and a plan of treatment. Sample cases: The Case of the Crying Baby: Surgical vs. Medical Management ; The Plan: Ethics and Physician Assisted Suicide ; The Haemophilus Vaccine: A Victory for Immunologic Engineering
Public Health – A case study describes a pandemic of a deadly infectious disease. Students work through the case to identify Patient Zero, the person who was the first to spread the disease, and how that individual became infected. Sample cases: The Protective Parent ; The Elusive Tuberculosis Case: The CDC and Andrew Speaker ; Credible Voice: WHO-Beijing and the SARS Crisis
Law – A case study presents a legal dilemma for which students use problem solving to decide the best way to advise and defend a client. Students are presented information that changes during the case. Sample cases: Mortgage Crisis Call (abstract) ; The Case of the Unpaid Interns (abstract) ; Police-Community Dialogue (abstract)
Business – Students work on a case study that presents the history of a business success or failure. They apply business principles learned in the classroom and assess why the venture was successful or not. Sample cases: SELCO-Determining a path forward ; Project Masiluleke: Texting and Testing to Fight HIV/AIDS in South Africa ; Mayo Clinic: Design Thinking in Healthcare
Humanities - Students consider a case that presents a theater facing financial and management difficulties. They apply business and theater principles learned in the classroom to the case, working together to create solutions for the theater. Sample cases: https://yaletmknowledgebase.org/category/case-studies/ .
Recommendations
Finding and Writing Cases
Consider utilizing or adapting open access cases - The availability of open resources and databases containing cases that instructors can download makes this approach even more accessible in the classroom. Instructors can consider in particular the National Center for Case Study Teaching in Science , a database featuring hundreds of accessible STEM- and social science - based case studies.
- Consider writing original cases - In the event that an instructor is unable to find open access cases relevant to their course learning objectives, they may choose to write their own. See the following resources on case writing: Cooking with Betty Crocker: A Recipe for Case Writing ; The Way of Flesch: The Art of Writing Readable Cases ; Twixt Fact and Fiction: A Case Writer’s Dilemma ; And All That Jazz: An Essay Extolling the Virtues of Writing Case Teaching Notes .
Implementing Cases
Take baby steps if new to CBL - While entire courses and curricula may involve case-based learning, instructors who desire to implement on a smaller-scale can integrate a single case into their class, and increase the number of cases utilized over time as desired.
Use cases in classes that are small, medium or large - Cases can be scaled to any course size. In large classes with stadium seating, students can work with peers nearby, while in small classes with more flexible seating arrangements, teams can move their chairs closer together. CBL can introduce more noise (and energy) in the classroom to which an instructor often quickly becomes accustomed. Further, students can be asked to work on cases outside of class, and wrap up discussion during the next class meeting.
Encourage collaborative work - Cases present an opportunity for students to work together to solve cases which the historical literature supports as beneficial to student learning (Bruffee, 1993). Allow students to work in groups to answer case questions.
Form diverse teams as feasible - When students work within diverse teams they can be exposed to a variety of perspectives that can help them solve the case. Depending on the context of the course, priorities, and the background information gathered about the students enrolled in the class, instructors may choose to organize student groups to allow for diversity in factors such as current course grades, gender, race/ethnicity, personality, among other items.
Use stable teams as appropriate - If CBL is a large component of the course, a research-supported practice is to keep teams together long enough to go through the stages of group development: forming, storming, norming, performing and adjourning (Tuckman, 1965).
Walk around to guide groups - In CBL instructors serve as facilitators of student learning. Walking around allows the instructor to monitor student progress as well as identify and support any groups that may be struggling. Teaching assistants can also play a valuable role in supporting groups.
Interrupt strategically - Only every so often, for conversation in large group discussion of the case, especially when students appear confused on key concepts. An effective practice to help students meet case learning goals is to guide them as a whole group when the class is ready. This may include selecting a few student groups to present answers to discussion questions to the entire class, asking the class a question relevant to the case using polling software, and/or performing a mini-lesson on an area that appears to be confusing among students.
Assess student learning in multiple ways - Students can be assessed informally by asking groups to report back answers to various case questions. This practice also helps students stay on task, and keeps them accountable. Cases can also be included on exams using related scenarios where students are asked to apply their knowledge.

Case Study | Definition, Examples & Methods
Published on 5 May 2022 by Shona McCombes . Revised on 30 January 2023.
A case study is a detailed study of a specific subject, such as a person, group, place, event, organisation, or phenomenon. Case studies are commonly used in social, educational, clinical, and business research.
A case study research design usually involves qualitative methods , but quantitative methods are sometimes also used. Case studies are good for describing , comparing, evaluating, and understanding different aspects of a research problem .
Table of contents
When to do a case study, step 1: select a case, step 2: build a theoretical framework, step 3: collect your data, step 4: describe and analyse the case.
A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case.
Case studies are often a good choice in a thesis or dissertation . They keep your project focused and manageable when you don’t have the time or resources to do large-scale research.
You might use just one complex case study where you explore a single subject in depth, or conduct multiple case studies to compare and illuminate different aspects of your research problem.
Once you have developed your problem statement and research questions , you should be ready to choose the specific case that you want to focus on. A good case study should have the potential to:
- Provide new or unexpected insights into the subject
- Challenge or complicate existing assumptions and theories
- Propose practical courses of action to resolve a problem
- Open up new directions for future research
Unlike quantitative or experimental research, a strong case study does not require a random or representative sample. In fact, case studies often deliberately focus on unusual, neglected, or outlying cases which may shed new light on the research problem.
If you find yourself aiming to simultaneously investigate and solve an issue, consider conducting action research . As its name suggests, action research conducts research and takes action at the same time, and is highly iterative and flexible.
However, you can also choose a more common or representative case to exemplify a particular category, experience, or phenomenon.

Prevent plagiarism, run a free check.
While case studies focus more on concrete details than general theories, they should usually have some connection with theory in the field. This way the case study is not just an isolated description, but is integrated into existing knowledge about the topic. It might aim to:
- Exemplify a theory by showing how it explains the case under investigation
- Expand on a theory by uncovering new concepts and ideas that need to be incorporated
- Challenge a theory by exploring an outlier case that doesn’t fit with established assumptions
To ensure that your analysis of the case has a solid academic grounding, you should conduct a literature review of sources related to the topic and develop a theoretical framework . This means identifying key concepts and theories to guide your analysis and interpretation.
There are many different research methods you can use to collect data on your subject. Case studies tend to focus on qualitative data using methods such as interviews, observations, and analysis of primary and secondary sources (e.g., newspaper articles, photographs, official records). Sometimes a case study will also collect quantitative data .
The aim is to gain as thorough an understanding as possible of the case and its context.
In writing up the case study, you need to bring together all the relevant aspects to give as complete a picture as possible of the subject.
How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methods , results , and discussion .
Others are written in a more narrative style, aiming to explore the case from various angles and analyse its meanings and implications (for example, by using textual analysis or discourse analysis ).
In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates.

Multiple Case Studies
Nadia Alqahtani and Pengtong Qu
Description
The case study approach is popular across disciplines in education, anthropology, sociology, psychology, medicine, law, and political science (Creswell, 2013). It is both a research method and a strategy (Creswell, 2013; Yin, 2017). In this type of research design, a case can be an individual, an event, or an entity, as determined by the research questions. There are two variants of the case study: the single-case study and the multiple-case study. The former design can be used to study and understand an unusual case, a critical case, a longitudinal case, or a revelatory case. On the other hand, a multiple-case study includes two or more cases or replications across the cases to investigate the same phenomena (Lewis-Beck, Bryman & Liao, 2003; Yin, 2017). …a multiple-case study includes two or more cases or replications across the cases to investigate the same phenomena
The difference between the single- and multiple-case study is the research design; however, they are within the same methodological framework (Yin, 2017). Multiple cases are selected so that “individual case studies either (a) predict similar results (a literal replication) or (b) predict contrasting results but for anticipatable reasons (a theoretical replication)” (p. 55). When the purpose of the study is to compare and replicate the findings, the multiple-case study produces more compelling evidence so that the study is considered more robust than the single-case study (Yin, 2017).
To write a multiple-case study, a summary of individual cases should be reported, and researchers need to draw cross-case conclusions and form a cross-case report (Yin, 2017). With evidence from multiple cases, researchers may have generalizable findings and develop theories (Lewis-Beck, Bryman & Liao, 2003).

Key Research Books and Articles on Multiple Case Study Methodology
Yin discusses how to decide if a case study should be used in research. Novice researchers can learn about research design, data collection, and data analysis of different types of case studies, as well as writing a case study report.
Chapter 2 introduces four major types of research design in case studies: holistic single-case design, embedded single-case design, holistic multiple-case design, and embedded multiple-case design. Novice researchers will learn about the definitions and characteristics of different designs. This chapter also teaches researchers how to examine and discuss the reliability and validity of the designs.
Creswell, J. W., & Poth, C. N. (2017). Qualitative inquiry and research design: Choosing among five approaches . Los Angeles, CA: Sage.
This book compares five different qualitative research designs: narrative research, phenomenology, grounded theory, ethnography, and case study. It compares the characteristics, data collection, data analysis and representation, validity, and writing-up procedures among five inquiry approaches using texts with tables. For each approach, the author introduced the definition, features, types, and procedures and contextualized these components in a study, which was conducted through the same method. Each chapter ends with a list of relevant readings of each inquiry approach.
This book invites readers to compare these five qualitative methods and see the value of each approach. Readers can consider which approach would serve for their research contexts and questions, as well as how to design their research and conduct the data analysis based on their choice of research method.

In this article, the researchers showed the importance of using technological opportunities in improving the education process and how they enhanced the students’ learning in science education. The study examined the connection between “Technological Pedagogical Content Knowledge” (TPACK) and belief system in a science teaching context. The researchers used the multiple-case study to explore the effect of TPACK on the preservice science teachers’ (PST) beliefs on their TPACK level. The participants were three teachers with the low, medium, and high level of TPACK confidence. Content analysis was utilized to analyze the data, which were collected by individual semi-structured interviews with the participants about their lesson plans. The study first discussed each case, then compared features and relations across cases. The researchers found that there was a positive relationship between PST’s TPACK confidence and TPACK level; when PST had higher TPACK confidence, the participant had a higher competent TPACK level and vice versa.
Recent Dissertations Using Multiple Case Study Methodology
Milholland, E. S. (2015). A multiple case study of instructors utilizing Classroom Response Systems (CRS) to achieve pedagogical goals . Retrieved from ProQuest Dissertations & Theses Global. (Order Number 3706380)
The researcher of this study critiques the use of Classroom Responses Systems by five instructors who employed this program five years ago in their classrooms. The researcher conducted the multiple-case study methodology and categorized themes. He interviewed each instructor with questions about their initial pedagogical goals, the changes in pedagogy during teaching, and the teaching techniques individuals used while practicing the CRS. The researcher used the multiple-case study with five instructors. He found that all instructors changed their goals during employing CRS; they decided to reduce the time of lecturing and to spend more time engaging students in interactive activities. This study also demonstrated that CRS was useful for the instructors to achieve multiple learning goals; all the instructors provided examples of the positive aspect of implementing CRS in their classrooms.
Li, C. L. (2010). The emergence of fairy tale literacy: A multiple case study on promoting critical literacy of children through a juxtaposed reading of classic fairy tales and their contemporary disruptive variants . Retrieved from ProQuest Dissertations & Theses Global. (Order Number 3572104)
To explore how children’s development of critical literacy can be impacted by their reactions to fairy tales, the author conducted a multiple-case study with 4 cases, in which each child was a unit of analysis. Two Chinese immigrant children (a boy and a girl) and two American children (a boy and a girl) at the second or third grade were recruited in the study. The data were collected through interviews, discussions on fairy tales, and drawing pictures. The analysis was conducted within both individual cases and cross cases. Across four cases, the researcher found that the young children’s’ knowledge of traditional fairy tales was built upon mass-media based adaptations. The children believed that the representations on mass-media were the original stories, even though fairy tales are included in the elementary school curriculum. The author also found that introducing classic versions of fairy tales increased children’s knowledge in the genre’s origin, which would benefit their understanding of the genre. She argued that introducing fairy tales can be the first step to promote children’s development of critical literacy.
Asher, K. C. (2014). Mediating occupational socialization and occupational individuation in teacher education: A multiple case study of five elementary pre-service student teachers . Retrieved from ProQuest Dissertations & Theses Global. (Order Number 3671989)
This study portrayed five pre-service teachers’ teaching experience in their student teaching phase and explored how pre-service teachers mediate their occupational socialization with occupational individuation. The study used the multiple-case study design and recruited five pre-service teachers from a Midwestern university as five cases. Qualitative data were collected through interviews, classroom observations, and field notes. The author implemented the case study analysis and found five strategies that the participants used to mediate occupational socialization with occupational individuation. These strategies were: 1) hindering from practicing their beliefs, 2) mimicking the styles of supervising teachers, 3) teaching in the ways in alignment with school’s existing practice, 4) enacting their own ideas, and 5) integrating and balancing occupational socialization and occupational individuation. The study also provided recommendations and implications to policymakers and educators in teacher education so that pre-service teachers can be better supported.

Case Study Definition
“What exactly is a case study?”
A case study critically assesses an event, a place, personality, or situation to draw a conclusion. It uses all background information to identify the key problems and recommend further action.
However, you must polish your analytical skills to master case study analysis.
A good case study demonstrates the excellent academic skills of students. But, planning is an important step, especially if you do not want to get into any complicated situation.
To help you write the case study easily, we have explained everything in detail in this blog. Here, you can learn all about the types of case studies and how to write one properly and successfully.

Paper Due? Why Suffer? That's our Job
Types of Case Study
Here are different types of case study that you are most likely to deal with in your academic years.
- Illustrative case study
- Exploratory case study
- Cumulative case study
- Critical instance case study
No matter what type you are writing, you will need to present detailed answers and explanations about the case study questions.
How to Start a Case Study?
“How is the case study done?”
Here are the steps that you need to follow for a smooth start to a case study writing process.
1. Identifying the Problem
The very first step in starting a case-control study is to identify the problem. For example, examining the incompetence of KFC to bring a substantial rise in the revenue.
2. Ponder the Root Source
Problems may originate from an incorrect marketing strategy or the flawed structure of the supply chain.
3. Create an Outline
Ask yourself, what should be the main points of the case study. You shouldn’t keep mixing methods and solutions in the essay. Gather at least 3 to 4 main points to explain in your case study and form an organized outline.
4. Potential Solutions
If you are a student, brainstorm and propose a solution to a social issue or any relevant topic. Keep in mind that different case study subjects have different requirements.
For example, in the business world, the marketing and sales teams write case studies to analyze how their products and services could solve the problems of potential customers. Or how their product would affect their social media audience.
How to Write a Case Study?
After making a basic case study analysis, there are some specific steps that you need to follow for writing a perfect case study. These are given below:
1. Introduction
Identify the key issue and write a solid thesis statement in 1-2 sentences. As with any other paper, your case study introduction should serve as a roadmap for your readers.
Your introduction should not only identify the research problem and its significance. But also discuss why this specific case is being written and how it relates to addressing the problem.
A good introduction must answer the following questions:
- What is being studied?
- Why is the issue important to investigate?
- How will this research advance new knowledge or ways of understanding?
2. Background Information
Incorporate relevant issues and facts and conduct extensive research on the problem. This is the point where you need to demonstrate how well you have researched your problem.
3. Alternative Solutions
Highlight alternative solutions for the problem to come up with the best solutions. Don’t forget to briefly outline the most viable solutions and evaluate their advantages and disadvantages.
4. Main Answer
Always provide a realistic answer to the question asked in the case. Explain the rationale for choosing the solution and justify it. Explain why this solution is proved to be the best and support it with solid evidence.
You can also utilize concepts from class discussions, lectures, and text readings to help your view. Make sure you have incorporated outside research and personal experiences if necessary.
5. Recommendations
Locate specific strategies to accomplish the solution. Suggest further actions and then outline the implementation plan.
Here are the points that you need to focus on when writing recommendations
- Choose which of the alternative solutions should be adopted.
- Briefly write about your choice and explain how it will solve the problem.
- Integrate the theory and coursework here.
These are the basic steps that you need to follow for writing any type of case study. However, you can add or remove the sections depending upon the requirements of the case study you are working on.
Case Study Research
A case study is a detailed study of a person, group, event, place, phenomenon, or organization. Case study methods are commonly used in social, educational, clinical, and business research.
A case study research design usually involves qualitative research methods, but in some cases, qualitative research is also used.
Case studies are great for describing, comparing, evaluating, and understanding different aspects of a research problem.
Case study research revolves around single and multiple case studies. It also includes quantitative evidence, relies on multiple sources, and benefits from the prior development of previous research.
Before starting writing your case study, research and think about what you want to learn or prove. You might be aiming to learn how a company develops a new product. You need to base your research questions around the purpose that you want to achieve.
Case Study Format
The only thing that matters, in the end, is the score. Figure out the required case study format and strictly adhere to it.
APA and MLA are the leading case study formats used in various institutions.
Writing a Case Study
Abstract adds to the spice of the paper. Try to craft a solid, brief, and sound abstract as it has immense power to impress or annoy your professors. A common reader also usually reads abstracts to decide if he wants to study the paper.
Have a look at the following components involved in proofreading. It can remove the mistakes and typos of your paper.
- Check for inconsistencies in the flow, structure, or content
- Check if the thesis statement is sound and clear
- Investigate the evidence to be relevant, productive, and credible
- Revisit formatting
How to Cite a Case Study?
Citing sources is an integral part. Four kinds of formatting techniques are used to cite case studies:
- Chicago style format
- Harvard style format
Case Study Outline
Let’s explore the way an outline is constructed in problem-oriented papers. Make sure that you outline your case study tactfully. You may find thousands of case study templates on the internet for your help.
Here are the main parts of mainstream educational case studies that you can follow.

Case Study Analysis
A successful case study analyzes a real-life situation and provides a great opportunity to gather evidence. It challenges existing assumptions about a problem and provides a new set of recommendations.
Critical thinking and analytical skills matter the most in case studies. They differentiate ordinary paper from outstanding one.
Ensure that your analysis goes through the following techniques.
Thoroughly read the case and brainstorm ideas for the different solutions. Do not rely on one solution.
Locate ideas that sound the most interesting, as they will form the solution. Be extra careful, as picking the wrong solution is the most common mistake.
Don’t rush to write the case study neatly in the first step. Take some time to build a neat one.

Case Study Report Prepared by University of Guelph
This section will provide you with an overview of case study reports and what components you should include when writing them.
What Will I Learn?
By successfully completing this section, you should be able to:
- describe what a case study report is and how it is used,
- identify the components of a case study and how they fit together, and
- explain why case studies are popular in business education.

Prepared by

In general, a case study is a historical or fictional description of a business situation. Case studies are stories that contain a particular management problem or decision that needs to be made. They are usually very detailed and contain information about key stakeholders, organizational processes, products, markets, financials, and so on.
The case study method of teaching plays an important role in management education (e.g., Banning, 2003) and is commonly used in management education programs (e.g., Conger & Xin, 2000). Case studies present vivid and engaging examples of realistic business situations that allow students to apply theoretical concepts (Barkley, Cross, & Major, 2005).
A Case Study Is:
a partial, historical, clinical study of a situation which has confronted a practising administrator or managerial group. Presented in a narrative form to encourage student involvement, it provides data—substantive and process—essential to analysis of a specific situation, for the framing of alternative action programs, and for their implementation, recognising the complexity and ambiguity of the practical world.
(Barnes, Christensen, and Hansen, 1994, p. 44)
As Barnes et al. (1994) explain in the definition above, an engaging case study will provide a managerial dilemma that models the complexity of real world business decisions. Moreover, these decisions need to be made considering the analysis of data, assessment of viable alternatives, proposed recommendations, and associated implementation plan.
Components of A Case Study Report
What should a case study report include.
The components of a case study report will vary depending on the preferences of your institution and instructor. Be sure to refer to your assignment instructions to find out what will be required in your context.
Most case study reports will include the following major sections and components:
- Cover page including basic student and class information
- Table of contents showing where key parts of the report can be found
- Executive summary of the key recommendations and points of the report
- Introduction to the report and identification of the focal problem being faced
- Analysis of the problem and application of course/program content
- Decision criteria and possible alternatives for solving the problem
- Recommendation for solving the problem
- Implementation plan for executing the recommendation and ensuring its success
- Exhibits that help to elaborate upon the content included in the report
- Reference list of any sources that were used at any point in the case study project
There are many possible subsections within these components. The following information provides a more detailed explanation of each component as well as specific strategies to help with writing.
Case Study Report Template
What are the components of a case study presentation.
The components of a case study presentation will likely also vary depending on the preferences of your institution and instructor; however, most case study presentations will likely include an oral as well as a visual (e.g., PowerPoint) summary of the 10 major sections and components. The case study report template provided will give you with a method for presenting your case study project as well as specific strategies to help with presenting the various sections.

The beauty market in 2023: A special State of Fashion report

The State of Fashion: Beauty
In 2022, the beauty market—defined as skincare, fragrance, makeup, and haircare—generated approximately $430 billion in revenue. Today, beauty is on an upward trajectory across all categories. It has proven to be resilient amid global economic crises and in a turbulent macroeconomic environment. Beauty is now an industry that many people, from top-tier financiers to A-list celebrities, want to be a part of—and with good reason. Following a solid recovery since the height of the COVID-19 pandemic, the beauty market is expected to reach approximately $580 billion by 2027, growing by a projected 6 percent a year (Exhibit 1). This is in line with or slightly higher than other consumer segments such as apparel, footwear, eyewear, pet care, and food and beverages.
About the authors
This article is a collaborative effort by Imran Amed, representing views from the Business of Fashion, and Achim Berg , Sara Hudson , Kristi Klitsch Weaver , and Megan Lesko Pacchia, representing views from McKinsey’s Consumer Packaged Goods and Retail Practices.
A dynamic segment that is ripe for disruption, the beauty industry will have reshaped itself around an expanding array of products, channels, and markets before this decade is over. Consumers, particularly younger generations, will spur this shift, as their own definitions of beauty morph while their perceptions of everything—from the meaning of sustainability and the role of influencers and key opinion leaders to the importance of self-care—evolve. Overall, beauty is expected to be characterized by “premiumization,” with the premium beauty tier projected to grow at an annual rate of 8 percent (compared with 5 percent in mass beauty) between 2022 and 2027, as consumers trade up and increase their spending, especially in fragrance and makeup.
At the same time, we expect the landscape to become even more competitive, as a range of independent brands that successfully came to market over the past decade seek to scale and as new challengers emerge. Intensifying competition will prompt incumbent brands and retailers to change as well. In line with the trend-driven dynamics in the market, 42 percent of respondents to McKinsey’s 2023 survey of consumers across China, France, Germany, Italy, the United Kingdom, and the United States say they enjoy trying new brands. Meanwhile, consumers are increasingly shopping across price points and report that both online and offline stores influence their shopping behavior. Their preference for omnichannel shopping is expected to continue to fuel legacy brands’ shift online and independent labels’ move into a brick-and-mortar presence.
E-commerce in beauty nearly quadrupled between 2015 and 2022, and its share now exceeds 20 percent, with significant runway ahead. This compares with a 2022 e-commerce share of approximately 30 percent in apparel and footwear, and around 65 percent in toys and games.
A number of factors have fueled e-commerce growth in beauty: the expansion of beauty offerings from online giants like Amazon in the United States and Tmall in China; the increased digital sophistication from direct-to-consumer players; the steadily growing significance of online for omnichannel retailers; and the proliferation of social selling, including livestreaming, in Asia. E-commerce is expected to continue to be the fastest-growing sales channel, at 12 percent per year between 2022 and 2027, but growth in traditional channels—including specialty retail, grocery retail, and drugstores—is expected to pick up postpandemic, as consumers’ preference for omnichannel is partly driven by their continued desire for in-store discovery and trial of products (Exhibit 2). Department stores are expected to continue to lose market share globally.
Structural and competitive dynamics are shifting
Where to play will become just as important a question as how to win, given the changing underlying growth tailwinds. The changing dynamics will render the industry’s largely homogenous global playbooks of the past decades less effective and require brands to reassess their global strategies and introduce greater nuance and tailoring.
Geographic diversification will become more essential than ever. It was just recently, for example, that brands could focus their footprints on the industry’s two top countries: China and the United States. Both countries will remain mighty forces for the industry, with the beauty market expected to reach $96 billion in China and $114 billion in North America by 2027 (Exhibit 3).
But in both markets, growth will be harder to come by for individual brands, not least due to fierce local and foreign competition. Meanwhile, other countries and regions, including the Middle East and India, are ready to step into the limelight, offering distinct potential for specific categories and price tiers. The likely upshot is that many brands will align their geographic strategies to this new world order, which will require a variety of localized playbooks.
Across geographies, another growth opportunity will be products and services in the top tier of the pricing pyramid: the true luxury and ultraluxury beauty market has the potential to double, from around $20 billion today to around $40 billion by 2027.
Five disruptive themes
The next few years will be a dynamic time for the beauty industry, filled with opportunities and new challenges. Its high profitability, with EBITDA margins of up to 30 percent, will continue to attract new founders and investors to the space. With limited spots available on the beauty palette, successful brands will adapt to the changing rules of the game and secure a uniquely differentiated value proposition amid a saturated market and increasingly sophisticated consumers. Key dynamics will include the following:
- The redrawing of the growth map. Slowing growth in China, along with increased local competition, means the country will no longer be a universal growth engine for the industry. As a result, the US market will become even more important, with strong growth, especially over the next few years. This market will become a competitive battleground for established brands and a potential green pasture for new entrants. The Middle East is expected to fuel growth over the same period, with India expected to emerge as a new hot spot in the longer term.
- The rise of wellness. As consumers are increasingly engaging with beauty products and services to not only look good but also feel good, the lines between beauty and wellness are expected to continue blurring, with the combined opportunity representing close to $2 trillion globally for brands, retailers, and investors. Wellness-inspired products—such as skincare and makeup with probiotic and Ayurvedic ingredients, ingestible supplements, and beauty devices like LED face masks—have already captured the attention of consumers embracing greater self-care and mindfulness in their postpandemic daily routines. The melding of wellness and beauty will only become more pronounced in the years ahead, in line with an expected CAGR of 10 percent to 2027 for the wellness industry. This trend will represent an untapped opportunity for many, with first-mover advantage for the players that get it right.
- The influence of Gen Z. Gen Zers scrutinize brands as part of their search for value. Nearly half of Gen Z respondents in our survey report conducting extensive research on product ingredients and their benefits before purchase, similar to millennials (and compared with only one-third of Gen Xers and one-fifth of baby boomers). Beyond product efficacy and transparency, Gen Zers demand that brands credibly stand for something. In addition to their focus on sustainability, diversity, and inclusion, Gen Zers greatly value brands that have an authentic and approachable image and a story that goes beyond products, and that welcome consumers into a wider community. Engaging with beauty products and services to feel good and express their authentic selves rather than adhering to specific cultural ideals, this cohort is challenging norms not only around the definition of physical beauty but also around gender and product categories.
- The imperative to scale. While the past decade has seen a number of new and independent labels benefit from steadily lower barriers to entry, growth beyond a successful initial run to achieve meaningful scale remains elusive for many. Out of 46 brands founded in or after 2005 with global retail sales of $50 million to $200 million by 2017, only five exceeded $250 million in global retail sales five years later, in 2022. Only two achieved global retail sales of more than $750 million. To scale successfully, brands must focus on omnichannel expansion and internationalization. Category expansion appears to be most effective when a brand has grown to a certain size, and when the expansion enhances and protects the brand’s unique value proposition.
- The recalibration of M&A. Amid continuously increasing interest in the beauty industry from a variety of players—from “strategics” to private equity funds—M&A will continue to play a major role in the industry. As seen in recent years, conglomerates and financial investors alike will pursue deals to invest in promising brands. But dealmaking will not be the same as when cost of capital was low. In the near term, megadeals will likely be few and far between in response to market turbulence. In addition, criteria for M&A targets will shift from a focus on high-growth independent “brands of the moment” to brands with an innovative product pipeline and a demonstrated ability to grow profitably, sustainably, and over the long term.
The years ahead will offer all the right ingredients—from agile channel mixes to consumers eager to explore new products—for the beauty industry’s continued growth. For beauty leaders and challengers alike, there will be plenty of opportunities to flourish, if they develop and execute tailored strategies that reflect the changing world of beauty.
