Note on the Case Method of Instruction

Note: Adapted in part from K. Davis, Marketing Management (New York: Ronald Press, 1972).

To really understand how managers make decisions, we would have to expose ourselves directly to the decision-making process. Unfortunately, we cannot project ourselves into actual business situations and make decisions. As a substitute, however, we can read descriptions of particular business situations and make decisions based upon the data we find there. By doing so, we can simulate the functioning of a manager.

Descriptions of business situations are frequently referred to as cases. A case is a statement of condition, attitudes, and practices existing at some particular time in a company's history. It usually describes a situation in which the company is facing some challenging problem or problems. A "case" differs from a "problem" in several respects. In the first place, a case typically contains several problems. Some of these problems may be self-evident, but more frequently, you have to identify the key problem or problems. One of the very real assets of the case method of instruction is that it forces you to identify problems. A second distinguishing feature of cases is the reality of the situations they describe. A "problem" might be posed as a question, "Should a manufacturer expand its product line?" or "Should the Vice President of Manufacturing be replaced?" or "Should the company increase its prices?" A case could suggest these or other problems, but by describing the conditions under which they arise we recognize that the real world is much more complicated than a single problem stated as a question. Indeed, we recognize that these questions should only be asked and answered in the context of a specific situation.

A case provides some, but usually not all, of the information that was available to executives at the time they had to resolve a challenging problem. It frequently includes data on alternative courses of action. Because it is an attempt to reconstitute a real life situation, a case is purposely written in a manner that requires the rearrangement of facts and interpretation of these facts, including the evaluation of opinions, behavior and intentions. Many of the facts available are relevant to the solution of the problem presented in the case, but some may be irrelevant. This arrangement of the descriptive material, on a somewhat unstructured basis, in itself simulates experiences of the business executive. Data that he or she has available for the solution of a problem are never orderly and systematically presented.

On first reading a case, you may well ask yourself, "What's this all about?" One of your first adjustments to the case method of instruction will be getting acclimated to the manner in which case material is presented. It will be up to you to develop your analytical ability by reorganizing the factual material and recognizing throughout this reorganization the particular problems involved.

You will have to develop the alternative solutions, gather the data relative to these solutions, evaluate them, and finally--and most importantly!--make a decision. In the course of your analysis, you will want to rely primarily on the substantive material that is presented in the case. But you will undoubtedly want to resort to the use of information and ideas that you have gathered in your general experience and in other courses. In addition, ideas developed from discussions with other students will provide you with much that is necessary to the solution of business cases.

In preparation of cases for classroom discussion, you will run up against the problem of insufficient information. By and large, each case has incorporated in it sufficient information to permit you to do an adequate job of analysis. Occasionally, however, certain types of data will be lacking, and your action plan may have to include as an early step the gathering of certain additional kinds of data. The absence of data, and the necessity of making assumptions about the nature of data, is likely to add some confusion in the early stages of studying under the case method of instruction. In many respects, this lack of information is a desirable aspect of cases, for business people likewise must make decisions under circumstances where they do not have all the necessary data.

To realize the maximum benefits while studying under the case method, you should recognize that:

  1. You are expected to participate actively in the class discussion. You should be prepared to be called upon for your analysis of the case, or of a particular issue within the case. A portion of your grade will be based upon the quantity of quality contributions you made to the discussion.
  2. In class discussion you should be prepared for a critical atmosphere; you should be willing to rebut the observations and conclusions of others and to have your ideas rebutted.
  3. The classroom is a "low risk" environment. Consequently you should be willing to take and defend "risky" positions. You can't lose money doing so, and your grade can only be improved through active classroom participation! Be willing to express your opinion--even and especially when it does not conform to the prevailing group opinion.
  4. The instructor is a discussion leader and not a lecturer or major contributor of facts and analysis.
  5. In each case you are expected to make defensible decisions. You will have to do so without all the data you would desire. This shortage of data is not a shortcoming of the case method; it is an accurate reflection of the environment in which management must make decisions.
  6. There may be several acceptable solutions to a problem in a case. The particular solution is not a significant as the reasoning (including assumptions) that leads to the solution proposed. Definitive answers are rarely available. Do not expect them from the instructor.
  7. Complete preparation of a case involves much more than simply reading the case as you would a story. No case included in the course requires less than two hours of preparation and some require much more. Each case requires you to do some numerical analysis and to outline the key points you would make to explain your analysis and to defend your action plan.
  8. You are urged to discuss each case with a small group of your fellow students prior to class. This discussion will illuminate issues that you may have overlooked and will inevitably improve your level of preparation for classroom discussion.
  9. Inevitably the same cases must be used from quarter to quarter and year to year. Most of the cases we will discuss have been used previously in other Stanford courses. Please do not use notes or written work from previous quarters as you prepare for classroom discussion or for papers. Learning by the case method is in the final analysis an individual proposition, requiring you to wrestle with the issues and analyze the facts. Case preparation is hard work. You will gain little from the course if you rely on others to do the work--students from previous quarters or your fellow students in this class.
