What is the Case Method?

The core pedagogy of Harvard Business School since the early 20th century, the case method boasts a unique ability to make complex concepts accessible and develop students’ leadership skills, all while creating an engaging intellectual atmosphere.

A “case” is a short narrative document – a story – that presents a particular challenge facing an individual or organization. Each case reflects the information available to decision-makers at the time, and builds to a particular decision point, but without revealing what decision was actually made. For each class, students are asked to read the case and to put themselves in the shoes of the actual decision-makers to consider what they themselves would have done given the information available at the time.

To help situate the decision, each case also provides background history on the most relevant issues and events leading up to the decision point. For example, a case that focuses on a decision facing Martin Luther King Jr. during the campaign for black voting rights in 1965 also traces the broader civil rights movement, as well as the history of segregation and black disenfranchisement in the U.S. since the Civil War.

In the classroom, the instructor poses questions to guide student discussion. These carefully designed questions are the key to any successful case-method course. An experienced case-method teacher is often thinking several steps ahead, anticipating what points and questions might be raised and standing ready with follow-up questions to guide the group. Active participation in class is essential to the case method’s success, and the grading metrics reflect its importance. Students quickly learn to speak up, to challenge each other, and to build on each other’s ideas.

Any professor or teacher can teach by the case method. Content expertise beyond the case itself is helpful but not required. To assist both experienced and new case-method teachers, each case has its own teaching plan: a flexible road-map for the instructor that suggests specific questions, strategies for eliciting key insights, and ideas for organizing student responses visually on a blackboard. For some cases, more extensive supporting documents known as “teaching notes” are available to fully brief the instructor on the relevant history and the multiple levels of questions he or she might consider.

“ I’ve never had this experience as a teacher before, and it's explicitly due to the case method — it's a game changer. ”

What the Case Study Method Really Teaches

Summary .   

During my decade as dean of Harvard Business School, I spent hundreds of hours talking with our alumni. To enliven these conversations, I relied on a favorite question: “What was the most important thing you learned from your time in our MBA program?”

• Teaching with Cases

At professional schools (like Harvard’s Law, Business, Education, or Medical Schools), courses often adopt the so-called "case method" of teaching , in which students are confronted with real-world problems or scenarios involving multiple stakeholders and competing priorities. Most of the cases which faculty use with their students are written by professionals who have expertise in researching and writing in that genre, and for good reason—writing a truly masterful case, one which can engage students in hours of debate and deliberation, takes a lot of time and effort. It can be effective, nevertheless, for you to try implementing some aspects of the case-teaching approach in your class. Among the benefits which accrue to using case studies are the following:

• the fact that it gives your students the opportunity to "practice" a real-world application;
• the fact that it compels them (and you!) to reconstruct all of the divergent and convergent perspectives which different parties might bring to the scenario;
• the fact that it motivates your students to anticipate a wide range of possible responses which a reader might have; and
• the fact that it invites your students to indulge in metacognition as they revisit the process by which they became more knowledgeable about the scenario.

Features of an Effective Teaching Case

While no two case studies will be exactly alike, here are some of those principles:

• The case should illustrate what happens when a concept from the course could be, or has been, applied in the real world. Depending on the course, a “concept” might mean any one among a range of things, including an abstract principle, a theory, a tension, an issue, a method, an approach, or simply a way of thinking characteristic of an academic field. Whichever you choose, you should make sure to “ground” the case in a realistic setting early in the narrative, so that participants understand their role in the scenario.
• The case materials should include enough factual content and context to allow students to explore multiple perspectives. In order for participants to feel that they are encountering a real-world application of the course material, and that they have some freedom and agency in terms of how they interpret it, they need to be able to see the issue or problem from more than one perspective. Moreover, those perspectives need to seem genuine, and to be sketched in enough detail to seem complex. (In fact, it’s not a bad idea to include some “extraneous” information about the stakeholders involved in the case, so that students have to filter out things that seem relevant or irrelevant to them.) Otherwise, participants may fall back on picking obvious “winners” and “losers” rather than seeking creative, negotiated solutions that satisfy multiple stakeholders.
• The case materials should confront participants with a range of realistic constraints, hard choices, and authentic outcomes. If the case presumes that participants will all become omniscient, enjoy limitless resources, and succeed, they won’t learn as much about themselves as team-members and decision-makers as if they are forced to confront limitations, to make tough decisions about priorities, and to be prepared for unexpected results. These constraints and outcomes can be things which have been documented in real life, but they can also be things which the participants themselves surface in their deliberations.

• The activity should include space to reflect upon the decision-making process and the lessons of the case. Writing a case offers an opportunity to engage in multiple layers of reflection. For you, as the case writer, it is an occasion to anticipate how you (if you were the instructor) might create scenarios that are aligned with, and likely to meet the learning objectives of, a given unit of your course. For the participants whom you imagine using your case down the road, the case ideally should help them (1) to understand their own hidden assumptions, priorities, values, and biases better; and (2) to close the gap between their classroom learning and its potential real-world applications.
