Learning by the Case Method
The case method is not only the most relevant and practical way to learn managerial skills, it’s exciting and fun. But, it can also be very confusing if you don’t know much about it. This brief note is designed to remove the confusion by explaining how the case method works and then to suggest how you can get the most out of it. Simply stated, the case method calls for discussion of real-life situations that business executives have faced. Casewriters, as good reporters, have written up these situations to present you with the information available to the executives involved. As you review their cases you will put yourself in the shoes of the managers, analyze the situation, decide what you would do, and come to class prepared to present and support your conclusions.

How Cases Help You Learn
Cases will help you sharpen your analytical skills, since you must produce quantitative and qualitative evidence to support your recommendations. In case discussions, instructors will challenge you and your fellow participants to defend your arguments and analyses. You will hone both your problem-solving and your ability to think and reason rigorously. Because case studies cut across a range of organizations and situations, they provide you with an exposure far greater than you are likely to experience in your day-to-day routine. They also permit you to build knowledge in various management subjects by dealing selectively and intensively with problems in each field. You will quickly recognize that the problems you face as a manager are not unique to one organization or industry. From this you will develop a more professional sense of management. In class discussions, participants bring to bear their expertise, experience, observations, analyses, and rules of thumb. What each class member brings to identifying the central problems in a case, analyzing them, and proposing solutions is as important as the content of the case itself. The lessons of experience are tested as different participants present and defend their analyses, each based on different experiences and attitudes gained by working in different jobs. Your classmates and you will differ significantly on what’s important and how to deal with common problems, interdependencies, organizational needs, and the impact of decisions in one sector of an organization upon other sectors.
Professor John S. Hammond prepared this note building on earlier notes by professors E. Raymond Corey and Martin Marshall of the Harvard Business School.


Learning by the Case Method

Perhaps the most important benefit of using cases is that they help managers learn how to determine what the real problem1 is and to ask the right questions. An able business leader once commented: “Ninety per cent of the task of a top manager is to ask useful questions. Answers are relatively easy to find, but asking good questions is the most critical skill.” The discussion questions suggested for each case are just to help you focus on certain aspects of the case. In presenting them the faculty is not preempting your task of identifying the problems in the case. You still must ask yourself: “What really are the problems which this manager has to resolve?” Too often, in real-life situations managers manipulate facts and figures without the problems having been specifically defined. A final benefit that the faculty seeks is to reinvigorate the sense of fun and excitement that comes with being a manager. You will sense once again that being a manager is a great challenge— intellectually, politically, and socially. In short, the case method is really a focused form of learning by doing.

How to Prepare a Case
The use of the case method calls first for you, working individually, to carefully read and to think about each case (typically about two hours of preparation time for each case are provided in the schedule). No single way to prepare a case works for everyone. However, here are some general guidelines that you can adapt to create a method that works best for you. 1. Read the first few paragraphs, then go through the case almost as fast as you can turn the pages, asking yourself, "What, broadly, is the case about, and what types of information am I being given to analyze?" You will find that the text description at the beginning is almost always followed by a series of exhibits that contain added quantitative and qualitative information for your analysis. Read the case very carefully, underlining key facts and writing marginal notes as you go. Then ask yourself: "What are the basic problems these managers have to resolve?" Try hard to put yourself in the position of the managers in the case. Make the managers’ problems your problems. Note the key problems or issues on a pad of paper. Then go through the case again. Sort out the relevant considerations for each problem area. Do appropriate qualitative and quantitative analysis. Develop a set of recommendations, supported by your analysis of the case data.


3. 4. 5. 6.

Until now, your best results will come if you have worked by yourself. However, if you have time before class, it is useful to engage in informal discussions with some of your fellow participants about the cases. This can be done at social hours, meals, or planned get-togethers. In fact, some people like to form discussion groups to conduct such discussions. (Discussion groups are important enough to be mandatory scheduled activities in many executive programs.) The purpose of these discussions is

Learning by the Case Method


not to develop a consensus of a "group" position; it is to help members refine, adjust and amplify their own thinking. To maximize the benefit to you of this group process it is extremely important not to skip or skimp on the individual preparation beforehand. If you take the easy way out and just familiarize yourself with the facts, saving all preparation to be done with your discussion group, you will deprive yourself of the opportunity to practice the very skills that you wanted to obtain when you enrolled.

What Happens in Class
In class, your instructor usually will let members discuss whatever aspects of the case they wish. The faculty’s job is to facilitate the discussion, to pose questions, prod, draw out people's reasoning, play the devil's advocate and highlight issues. A healthy debate and discussion will ensue. You will benefit most if you participate actively in that debate. Sometimes faculty will present conceptual frameworks and invite you to use them to organize your thoughts to create new insights. Other times they’ll generalize, summarize, or tell about relevant situations in other companies. They'll try to keep the discussion on track and moving forward. To do this, they’ll usually organize and document the on-going debate on the blackboard. While faculty may suggest the pros and cons of a particular action, only occasionally will they give their own views. Their job isn't to help the class reach a consensus; in fact, often the thought process will be far more important than the conclusions. Near the end, instructors will summarize the discussion and draw out the useful lessons and observations which are inherent in the case situation and which emerge from the case discussion. A typical request at the end of a discussion is “What‘s the answer?” The case method of learning does not provide the answer. Rather, various participants in the discussion will have developed and supported several viable “answers”. Business is not, at least not yet, an exact science. There is no single, demonstrably right answer to a business problem. For the student or business person it cannot be a matter of peeking in the back of a book to see if he or she has arrived at the right solution. In every business situation, there is always a reasonable possibility that the best answer has not yet been found—even by teachers.2 Sometimes when the faculty knows the outcome of the case they'll share it with you at the end of the discussion. While it is fascinating to learn how things actually turned out, the outcome isn't the answer either. It is simply one more answer, which you may feel is better or worse than yours. What is important is that you know what you would do in that situation and, most importantly, why, and that your skill at arriving at such conclusions has been enhanced. You can't acquire judgment and skill simply by reading books or listening to lectures any more than you can become a great swimmer just by reading a book on swimming. While the knowledge obtained from books and lectures can be valuable, the real gains come from practice at analyzing real business situations.

How You Can Get the Most Out of the Process
There are a number of things you can do to get the most out of the process: 1. 2. Prepare. Not only is a thorough, individual preparation of each case a great learning experience, it is the key to being an active participant in the case discussion. Discuss the cases with others beforehand. As mentioned earlier, this will refine your reasoning. It's not cheating; it's encouraged. However, you'll be cheating yourself if you don't prepare thoroughly before such discussions. Participate. In class, actively express your views and challenge others. Learning by talking may seem contrary to how you learned in other settings. You may have been urged to be silent and learn from others, especially the faculty. In case discussions, when you express your views to others you commit which, in turn, gets you involved. This is exactly the same as betting at the racetrack; your bet is a commitment which gets you involved in the race. Talking forces you to decide; you can no longer hedge. Share your related experience. During class if you are aware of a situation that relates to the topic being discussed and it would enrich the discussion, tell about it. So-called war stories heighten the relevance of the topic. Constantly relate the topic and case at hand to your business no matter how remote the connection seems at first. Don’t tune out because of a possible disconnect. You can learn a lot about marketing insurance by studying a case on marketing razor blades and vice versa. It’s not whether it relates, but how. Actively apply what you are learning to your own, specific management situations, past and future. That will greatly heighten relevance. Even better is to pick a situation that you know you will face in the future where you could productively use some good ideas. For example, how can I grow my business? Make note of each good idea from the discussion that helps. Not only will these ideas improve the outcome of the situation, they will stick in your mind forever, because they were learned in the context of something important to you. Note what clicks. Different people with different backgrounds, experiences, skills and styles will take different things out of the discussions. Your notes will appropriately be quite different from your neighbors’. Mix it up. Use the discussion as an opportunity to discover intriguing people with different points of view. Get to know them outside of class and continue your learning there. Try to better understand and enhance your own management style. By hearing so many other approaches to a given situation you will be exposed to many styles and thereby understand your own. This understanding will put you in a better position to improve it.






8. 9.

You will learn from rigorous discussion and controversy. Each member of the class—and the instructor—assumes a responsibility for preparing the case and for contributing ideas to the case discussion. The rewards for these responsibilities are a series of highly exciting, practically oriented educational experiences that bring out a wide range of topics and viewpoints.

Case Study Methods

...Case-Study Method and Report Guidelines Why case studies? “Decision making is what managers do, so do Project Managers” The decisions of managers directly influence revenues, costs, and profits of an agribusiness firm. If you are to be successful in a management career, you must learn to be a good decision maker. You must develop the ability to apply classroom training in business and economics to problem solving so that you can learn how to (1) make decision making easier, (2) improve the analytical quality of decisions, (3) reduce the time required to make decisions, and (4) increase the frequency of correct decisions. As you discuss cases with your fellow students, you will learn that decision making is often a confrontational activity involving people with different points of view. Most important, you will learn how to work toward consensus while tolerating legitimate differences of opinion. The Seven Steps of Problem Analysis 1. Read the case thoroughly. To understand fully what is happening in a case, it is necessary to read the case carefully and thoroughly. You may want to read the case rather quickly the first time to get an overview of the industry, the company, the people, and the situation. Read the case again more slowly, making notes as you go. 2. Define the central issue. Many cases will involve several issues or problems. Identify the most important problems and separate them from the more trivial issues. After identifying what appears to be a major...

Case Study Method

...Case Study Method The case method of teaching is widely used in business and science education today. By definition, a case is a written account of an actual condition that has occurred. This account is used as a real life example of a situation that can be analyzed by the students to teach concepts related to course study. Most often teaching with the case method requires facilitation and discussion of the account by the students (Foran, 2002). The aim is to analyze and apply the various course concepts as they pertain to the events in the case study. Some of the tools used by the teacher in the case method may be debate, or collaboration by placing students in groups. William Perry is a psychologist professor at Harvard and has commented on what is known as the Perry model for student learning. During early education students learn in what is called the dualist mode, where educators are the authority figures that students model and accept as 100% accurate in everything they say (Herreid, 2004). These authority figures lecture them on what is right and wrong and the students do not question this authority. The answers given by the teachers are the only correct ones and so the student learns to memorize these answers. During tests these answers are the only ones accepted as correct. Perry notes that this lecture mode only emphasizes the dualist mode where students are not allowed to think for themselves. He also makes the point that this is not how science works (Herreid...

Case Method on Le Chateau

...A) DEFINITION A case method is a documented study of a situation that transpires in real life or it can be about a fictional situation, which is used as teaching or learning tool in business schools and firms. These studies allow students evaluate cases and provide their own interpretations on potential solutions for the provided business scenario. Furthermore, the case method can also be described as something that gives you a detailed explanation of a company, industry, person, or project over a given period of time. Within the explanation, information about the company’s objectives, strategies, challenges, results, recommendations and more can be found. This also poses as a great way to promote interaction between students and instructors to propose insights about the issues in hand and share it with the class. Thus, the case method allows students to get an exposure to the actual functioning of business and other administrations in the real world, make managerial decisions bases on theories and views and enhance students ability to problem solve and make decisions. B) USE Case studies can be utilized in various instances such as class discussions, a company, in management education, etc. Apart from this, the uses of case studies have a variety of benefits. They develop real life business leadership skills, assist in making lectures more engaging and teachable, and help prepare for business settings that require decision-making and develops a better understanding...

Description Janet was a young girl that grew up in an abusive household that was beaten by her father as a part of a discipline process. Her father never explained why he used such drastic measures, so she grew up thinking that this was acceptable. She presumed that the only way to earn his love and respect was to do better. There was only one positive influence in her life; an aunt, who was rarely around because of the distance between them. Janet learned early to associate love with fear and trying with failure. As Janet grew older, she began to learn that her father might have been wrong. She began to see the regret coming from those actions, and soon realized that she had control.

...Question 1 Many organizations frequently rely on the insight of consultants to assist them in identifying areas of opportunity, making highly impactful decisions, and gaining additional insights as to the forthcoming direction of their industry. Some of the largest and most reputable consulting firms, such as Booz Allen and McKinsey, work on a global scale with internal divisions that specialize in a number of varying industries. The concept of consultants has been of great debate for many years, as some believe that if there is good management in place, they should be able to lead their organization appropriately without the help of expensive teams from the outside. However, one must remember that a great deal of what makes the daunting price tag of consultants an easily justifiable expense is the extraordinary weight the opinion of outside consultants carries with key influential decision makers. A Forbes magazine article on the topic says, “It really is often about being able to say “XYZ Consultants Inc recommend we do this” as that carries more weight in the internal arguments than “I say we do this” (Worstall, 2012). As a manager at a life insurance company, there a a number of things I would be looking for in the business report I received from the consulting firm I hired before I deem their findings valid.

Case Study Method

...CASE METHOD Case study method is said to consist of several deficiencies. In spite of that, it is widely used in management education and training. Many arguments are made for using the case study method for imparting management education. Some of these arguments are: a) Translating Knowledge into Action: The texts always provide the concepts and their logical sequence. The success or failure of the manager depends more on his action and dynamics rather than his conceptual knowledge. The case enables one to decide about the action in a given situation and then relate it to the textual knowledge. The shuttling between precepts and practices will be possible while dealing with a case situation. (b) Opportunity to Analyze: In a case, a reader is getting a good opportunity to analyze and find out the ingredients. While the text gives standard principles, the application would vary based on the actual situations. One who reads the case gets an opportunity to diagnose the problem, evaluate alternatives and finally select a mode of operation that may be right or wrong. Several such decisions will enable one to become an adept decision maker. (c) Opportunity for Self-Determination: In a case study situation, all decisions are taken by the one who reads the case rather than any imposition of answers or solutions by anybody else. Practice makes a man perfect. Cases provide ample opportunities for self determining the case solutions based on one's own analytical and decision...

Case Method Outline

...CASE ANALYSIS A case analysis method of study provides experiential education—learning by doing. Therefore, the amount of learning students receive from an individual case is directly related to the amount of work they put into it. A major goal of the use of cases is to allow students to gain experience in problem solving. Cases help students learn to: • develop an understanding of problems, • learn how to dissect the various factors relevant to a problem, • learn how to think creatively about solutions to a problem, • learn to critically and thoroughly evaluate alternative solutions, • learn how to make a final decision—one that you are willing to move forward with and one that you feel confident in supporting. Through the use of cases, students learn that the most obvious solution is not always the best solution. The only way to discover a “best” solution is to consider all (the emphasis here is on the ALL) possible alternatives, to identify the potential positive and negative outcomes for all alternatives possible, and then to select which alternative course of action seems best, based on their analysis, and marketing theory, concepts, and principles. Students need to understand the basic factual and theoretical foundations for marketing management...

The length of the assessment should be between three and five pages with “1.5” line spacing and margins of one inch and 12pt. font. You should organize the paper with subheadings corresponding to the four following sections. Avoid bullets – you must make connections and articulate what a factor/issue means in the situation and how it influences other factors/issue and possible actions etc. You must demonstrate relevance. In general, please focus your energy on the content and the quality of your assessment. NOTE: This is not a summary of the case but a true case analysis. 1. Problems statement — please, state the “problem” using one paragraph and a few sentences. Try to be clear, precise and concise. Try to formulate the problem from the perspective of the decision maker by highlighting the decision that must be made, the “tasks” he or she has to perform, and the issues that he or she is facing. 2. Situational analysis — this is the “meat” of the case brief, and as such it should be the longest section of the paper. Please do not just repeat the facts of the case.

...Business Case for HR Self Service Systems Table of Contents Executive Summary 3 Project Overview 3 Business Case for Proposed Project 4 Conclusion 5 References 5 Executive Summary This paper addresses the business case for implementing self service in the IT industry with the aim of gaining higher efficiency for a majority of HR functions and other benefits that can be derived from improved information access. The paper also discusses the various challenges an organization might face while attempting to implement self-service. The business case for self service revolves around reducing administrative costs and gaining better efficiency. It also aims at improving the overall performance and other benefits such as information management, trend analysis and also operational efficiency. The chief argument presented here is that a self-service initiative allows the HR to concentrate more towards the core functions such as people management instead of getting burdened with administrative tasks. While self-service has the ability to improve the service expectations from HR, it may also result in some of the savings being consumed in order to meet the higher quality expectations. However, on the long run, it is bound to reduce expenses to a great extent while enhancing the quality. Self-service also enables an organization to implement flexible work and helps employees to remain connected with the organization through a centralized HR system aimed at remote...

These data are usually strongly influenced by the consolidated experience of the operators, by the specific previous similar machining cases and by several other factors depending on the machining practices. In a project, financed by the Swiss national organization for the industrial research, the authors have developed an expert system (ES) in order to get this information through software processes. The paper shows the structure of this expert system. The ES has been realized through the definition of ontology of components and elements of the machining. The ES includes a very large data base of cutting parameters, and is based on the establishment of rules for the competition between the machining strategies. The ES includes learning methods which are able to identify similar operations. The learning methods are based on the measure of the distance between the actual machining conditions and those already experimented. Therefore the system is able to learn from similar cases. The system has been designed especially for an application in the field of the watch industry which requests a very large spectrum of machining operations and includes also the cases of the HSC.

...the meeting, the interviewer mentioned that Multi Tech uses structured analysis and relies heavily on modeling, prototyping, and CASE tools. Thinking back, you realize that you did not fully understand those terms. As you prepare for an interview with Rainbow's End, a large retail chain, you decide to review some IT terms and concepts. You want to be ready for the following questions: What are the main differences between structured, O-O, and agile development methods? There are several differences between structured, Object-oriented, and agile development analysis methods. Structured analysis employs processes and data separately, whereas Object-oriented uses objects to represent the data and related processes. Object-oriented analysis also takes advantage of object models that combine data, object behaviors, as well as how objects interact and interact with each other. With O-O, the objects and object models can be reused and customized as new needs arise. The combination of the data, processes and object behaviors, along with reusable models, makes the Object-oriented method flexible and more efficient when compared to the more rigid structured analysis ((Shelly & Rosenblatt, 2012, p. 21). The Agile analysis method is normally based on a spiral model that involves revisions developed through feedback from users. While the Agile method can be more flexible and can lead to less risk and better development time, it can still be risky if the user feedback is not...
