INTRODUCTION
A
re you a student who is new to the case method? Are you a student
who feels that you aren’t learning as much as you want from the
case method? If you belong in either of these categories, this book
was written for you.
The first edition of The Case Study Handbook emerged from my sixteen
years of work with business school students. This new version follows over
a decade more of working with students and refining the ideas in the first
edition. The initial motivation for the book was frustration. I had been
trying to help Harvard Business School MBAs write better case-based
examinations. I gave them what I considered to be good advice about
writing, such as using a logical essay structure and being concise. There
was nothing wrong with the advice—I’m still giving it to this day—but
it didn’t have the positive impact I expected on the quality of students’
exam essays.
Eventually, I realized that I didn’t fully understand what the students
were having trouble with. First, my advice started in the wrong place. I
assumed that students knew how to analyze cases to provide the content
needed for their exam essays. Actually, many weren’t sure how to do that.
Their uncertainty compromised the depth and quality of their thinking
about cases.
Second, case examinations usually ask students to take a position on
the central issue of a case. Although many students had no problem taking
a position, they weren’t certain what else they needed to do. A common
strategy was to fi ll the essay with case facts the students thought were relevant to their position and let the reader sort out the relationship between
the facts and the position. I assumed that they knew how to write an
argument to prove their position.
The two issues had nothing to do with how smart the students were.
They weren’t at fault for not knowing what they needed to do because no
one had ever told them. Students are usually expected to figure out how
to analyze cases on their own. Many do and many don’t. But the process
of making cases meaningful is too important to leave to chance. The rich

learning that the case method offers can’t be completely realized unless
students—meaning you—understand what a case is and how to analyze
it. The same is true of understanding how to make evidence-backed
arguments.
One other aspect of the case method causes problems for a significant number of students: classroom discussion of cases. They’re unsure
of the purpose of discussion and their role in it. Much of this uncertainty
stems from students’ educational backgrounds. They’re used to the lecture
method and have honed the skills needed for that method of instruction:
listening and taking notes. They emphatically aren’t used to the professor
asking them questions or having a major share of the responsibility for
learning in the classroom.
It’s telling that three critical aspects of the student role in the case
method—analysis, discussion, and argument—are often ignored. The
case method has been defined largely from the point of view of professors,
not students. Professors concern themselves with analyzing cases in order
to teach them and are skilled in argumentation. However, what matters
most in the classroom is what students, not professors, know—or don’t.
I’m not blaming professors. They’re focused on their subject-matter
expertise, and the academic reward system tends to be biased toward what
the professor knows, not how well she or he can teach that knowledge.
Showing students how to analyze cases and make arguments about them
falls outside the lines of business disciplines and the organization of business departments or schools. You’ll look in vain for a Department of Case
Analysis.
This book fi lls the gap I’ve just described in traditional business curricula. (It also is relevant to programs other than business that use cases,
including medicine, nursing, and engineering.) It provides:
• Analytical tools that help you sort, organize, and reflect on the
content of a case and use the concepts and frameworks taught in
business courses more effectively.
• Advice on how you can participate in and contribute to classroom
discussion of cases.
• Guidance on how to develop arguments about cases and express
them in writing that is logical, clear, and succinct.
It’s a fair question to ask whether the advice in this book works. Is it
worth your time to read? Here’s what I can tell you. For over a decade
since the publication of the initial edition, a group of writing coaches,
including me, has used the first edition of the book as a foundation for our

INTRODUCTION3
work with hundreds of Harvard MBAs. Almost all of our students significantly improved their ability to analyze cases and to write about them.
Our metric was the grades that students received. I’ve had similar results
in my teaching at Brandeis University, George Washington University,
and the University of Miami.
One of the best examples from my own coaching is a first-generation
college graduate from a family that had emigrated to the United States
when he was a child. He received poor grades on his first-year exams
at HBS and was understandably demoralized. He used the concepts in
this book to enhance his understanding of how to analyze a case and
write a persuasive argument about it. In his second year, he received high
grades in all of his courses—a complete turnaround from his first year.
There were several reasons for his academic improvement, the primary
one being his hard work. But he said he also benefited in class discussion
and on exams from the concepts drawn from this book.
This book uses Harvard Business School cases as examples and includes
analyses of them. Don’t assume, however, that the analyses give the “right
answers” to the cases. The evidence in them can sustain other conclusions. The book also includes essays about the cases; they are based on the
writing of MBA students. Because the original essays were examinations
written under time pressure, they inevitably had errors, unclear sentences,
and lapses in logic. I debated whether to present the essays as is or correct
and revise them. I chose the latter. No essay is perfect, and I don’t want to
set a standard of unobtainable perfection. But I want you to have the best
examples of the points made in the book without confusion over what is
correct and what isn’t.
This book is intended for you—case method students current and prospective. My wish is that it will enhance your learning from cases and
provide benefits for others associated with your learning—your peers,
professors, employers, colleagues, and communities.

CHAP TER 1
WHAT IS THE CASE
METHOD? WHAT’S
IN IT FOR YOU?
E
ach year, entering business school students— and students in many
other disciplines— encounter an approach to learning that is new to
them: the case method. You may be one of them. For novices, the
first encounter can be frustrating and unnerving. A case appears to be a
straightforward narrative, but when you finish reading it, you may ask
yourself questions such as:
• What point is the case trying to make?
• Is it trying to make a point at all?
• What am I supposed to do now?
Let’s say you have read a case study of a restaurant chain that ends with
the CEO turning over in his mind basic questions about the business.
He has some possible answers, but the case doesn’t tell you which one
he thinks is best. In another case study, a young MBA has accidentally
learned of office behavior that could have serious consequences for the
individuals involved, including her. At the conclusion of the case, she has
a literal and figurative headache, and the choice of what she should do is
left up in the air.
In the classroom, case instructors facilitate discussion, asking lots of
questions, writing comments on the board, and making occasional
remarks. Students respond to questions, build on each other’s comments,
disagree with one another, ask questions, and try out different points of
view about the case situation. A case classroom is dynamic and unpredictable; discussion can lurch into a blind alley, reverse course, and then
head in a more productive direction. Sometimes the discussion may seem
to end in a frustrating muddle. Students have expressed confl icting views
about the main issue in the case, and the professor, the expert in the room,

6THE CASE STUDY HANDBOOK
doesn’t step in and resolve the confl ict by announcing the “right” answer.
Why doesn’t she do her job?
Actually, she is doing her job. In a case classroom, you’re entitled to your
own opinion; you don’t have to defer to the professor or other students as
long as you back your opinion with case facts (including numbers when
they’re available) and fact-based inferences and calculations. The professor
doesn’t lay out the correct response to the case for one very good reason. As
students, you have to learn how to think. The professor can’t do it for you.
You have to practice thinking, which means you’ll gain insights and understanding that are gratifying and fun and make mistakes that are frustrating.
Written examinations that use cases pose another challenge for you. In
class, everyone, including the instructor, works collaboratively on a case.
On exams, you are on your own. You not only have to analyze the case
in response to one or more questions but also write an essay that satisfies
and persuades an expert reader, all in a limited time.
WHAT’S IN IT FOR YOU?
Until now, your education has probably consisted primarily of lectures.
They are widely used all over the world. There are good reasons for their
popularity. They are an efficient way for an expert to deliver content to
many individuals at once. One memorable description of the method is
the “sage on the stage.” In combination with textbooks, which are lectures in print, this learning model can deliver a large amount of content
to many students in a short time. In addition, student learning can usually
be tested efficiently with multiple choice or short-answer questions or
problem sets.
The lecture model is good for transferring information. In that sense, it
is efficient (although there are serious questions about how long and how
well students retain the information). However, like any learning model, it
has limitations when used exclusively. Most important, lectures can teach
you what to think but not how to think. Lecture content (live or delivered
through media such as the web and in textbooks and other similar readings) provides theory, frameworks, concepts, facts, formulas, and expert
opinion about a subject. It is the “what” of thinking.
However, for knowledge you will use in the real world—in business, for
example, or in engineering or medicine—the “what” isn’t sufficient. You
must know how to apply the knowledge in the real world. For that, you
need to practice in situations that are similar to those you will actually
encounter.

WHAT IS THE CASE METHOD? WHAT’S IN IT FOR YOU?7
Here’s a simple example of the difference between what and how. You
received a degree from Soccer University. You took courses on rules,
skills, and strategy and read textbooks, listened to lectures, and watched
videos and demonstrations by professional soccer players. However, you
never practiced what you learned on a soccer field. Do you know how to
play soccer? No, you don’t.
Similarly, let’s say you’re an MBA who took multiple accounting classes
taught by the lecture method and read the assigned textbook. None of
your classes used cases or any other type of active learning. In your first
job, you’re asked to evaluate the organization’s accounting system. In
school you had lectures on different types of accounting systems, but you
were never asked to analyze, on your own, a real-world accounting system
and its fit with an organization. You aren’t sure what criteria you should
use. You could tell your boss that you need her help but are afraid she
might question the decision to hire you.
One area of education has always recognized the importance of both
the “what” and the “how.” Medical schools teach their students knowledge from a wide range of fields (the what). But it would be unthinkable
to teach students the theory of medicine and turn them loose on patients
with no training in how to treat them. Medical schools require clinical
training: the application of what students have learned to real patients
under the supervision of experienced doctors (the how). This practice
continues beyond graduation from medical school in internships and
residencies.
Strangely, academic disciplines that teach knowledge meant to be
applied in the real world often put limited or no emphasis on the translation of knowledge into action. This knowledge requires practice opportunities. The lecture method generally doesn’t give students the chance to
practice. In the case method, you use the knowledge you have learned to
come up with your own answers (with the guidance of an expert). The
method allows for answers that are objectively wrong or dubious because
they are part of learning. The case method allows you to make mistakes
and learn from them.
This fundamental shift in the learning model causes many students to
be confused, uncertain, and anxious. But professors using cases are doing it
for your sake. They want to give you the opportunity to practice using what
they’ve taught you.
Think of it this way: when you are in a job, your professor isn’t going
to be there to tell you the right answer. Your boss likely isn’t going to tell
you either. After all, she hired you to come up with answers.

8THE CASE STUDY HANDBOOK
SKILLS FOR THE CASE METHOD
MBA students have told me they feel there is a secret to the case method
that some people get and some don’t. If you get it, you do well; if you
don’t, you scrape by as best you can.
The case method requires a lot from you. At the same time, it isn’t a
secret society in which a few fortunate individuals get it and outperform
their peers. As a case method student, you need three distinct sets of skills:
1. You need to be able to read a case and give it meaning in relation
to the key issues or questions that you have been asked about it.
2. You have to be able to communicate your thinking effectively in a
class discussion.
3. You must be able to write a persuasive response to a question about
a case.
Reading, discussing, and writing about cases all involve the application
of knowledge to the situation described in a case. What does “knowledge”
mean? It includes your work experience and also the knowledge you learn
in courses such as the principles of accounting, the 5Cs of marketing, and
the Five Forces of Michael Porter.
This book addresses the three aspects of the case method. The case
method begins with reading a case, interrogating it with questions, seeking information relevant to the questions, making inferences and calculations, and forming an opinion or conclusion about the main issue. These
skills are the focus of part I of this book. In the classroom, the case method
is about sharing your thinking with classmates and the instructor and
learning from this collaboration. The skills related to case discussion are
the subject of part II. You may have to write about cases for class assignments or the final examination. Skills for writing about cases are covered
in part III. In part IV, you’ll find three cases used as examples for analyzing
and writing about a case. Finally, part V includes Study Guides for taking
notes to prepare for case discussion and to outline a case-based essay.

WHAT IS A CASE?
H
ave you ever read a case? If you haven’t, this chapter will be much
more useful to you after you have read a case. There are three at the
end of this book to choose from. Read the first section of the case
slowly and skim the rest to get a sense of the story it tells.
Much of what you read daily is packaged to make it easy to understand.
The writing in newspapers, magazines, television, internet resources such
as Facebook, and academic articles tells you what it means. If it doesn’t, it
has failed in its purpose to inform. A newspaper article, for example, states
its subject clearly, often in the first paragraph, and carefully declares its
main points, which are usually explained and amplified through specific
examples.
Here are the first two paragraphs from a column written by Steven
Pearlstein of the Washington Post:
In the recent history of management ideas, few have had a more profound—
or pernicious—effect than the one that says corporations should be run in a
manner that “maximizes shareholder value.”
Indeed, you could argue that much of what Americans perceive to be
wrong with the economy these days—the slow growth and rising inequality;
the recurring scandals; the wild swings from boom to bust; the inadequate
investment in R&D, worker training and public goods—has its roots in this
ideology.1
After you read these two paragraphs, you know what the subject of the
article is. You also have an expectation about the content of the rest of the
article: it will explore the specific ways in which maximizing shareholder
value has led to serious economic problems.
You have probably read parts or all of hundreds of textbooks. Along
with lectures, they are the backbone of university education. Both are
invaluable for learning about ideas that have proven useful to understanding the real world. For example, in strategy courses all over the
world, students learn about Michael Porter’s Five Forces. His framework
helps organize thinking about the economic factors that determine how

12ANALYZING CASES
competitive industries are. They help you see the elements underlying
strategy and how organizations orchestrate them—or don’t. Theories and
frameworks help you make sense of specific types of situations in the real
world. Without them, you would be far less able to explain or anticipate
events such as the astonishing success of an organization (e.g., Uber) or a
shocking reversal of fortune (Uber). The knowledge codified in concepts
and theories taught in academic disciplines is indispensable for understanding the world.
At the same time, educational texts represent reality as logical and
coherent. They can make a complex situation that surprised everyone,
including experts, and affected millions of people around the world
appear to be the logical outcome of well-defined causes. The financial
crisis of 2007–2008 that started in the United States and spread around
the world is an example. Few people saw it coming, and experts, industry
participants, government regulators, politicians, journalists, and victims
were shocked when it happened. But afterward, experts found a pattern
of actions that they believe led inexorably to the disaster.
We can learn much from the study of past events. In real time, however, real-world situations have islands of useful data, observations, and
reference points but, to participants, are often fluid and chaotic, have a
large degree of uncertainty, and are difficult to understand. Real-world
situations don’t come with carefully selected and sorted information that
tells participants what is going on and what they should do about it.
To practice using knowledge in actual situations, you need some way of
immersing yourself in both the available facts and the fluidity and uncertainty that characterize the real world. That’s what cases are for.
WHAT A CASE IS, WHAT IT DOES,
WHAT IT DOESN’T DO
A business case imitates or simulates a real situation. By case, I mean
the substantial studies from universities or corporations, not the slender
vignettes sometimes included in textbooks. Cases can also be collections
of articles, multimedia content, or a variety of other types of content.
They are verbal representations of reality—sometimes with visual and
auditory complements—that put you in the role of a participant in a situation. The subject of cases varies enormously, from a single individual or
organization to an entire nation. Printed cases can range from one page to
fi fty or more and can have a small or large amount of content. But all of
these different forms of cases have a common purpose: to represent reality,
to convey a situation with all its crosscurrents and rough edges.

WHAT IS A CASE?13
Cases are an analogue of reality—an avatar, if you like—for the direct
experience of business or other types of activities. They immerse you in
certainties and vagaries. To perform this function, a case must have four
characteristics:
• A significant business issue or issues
• Sufficient information on which to base conclusions about the
issues
• No objective conclusion—in other words, no explicit or implied
right answer
• A nonlinear organization
Let’s explore each of these characteristics.
Significant Issue
A case without a significant issue has no educational value. You can therefore assume that every case deals with something important in the real
world, for example, a pricing dilemma, debt-equity trade-offs, or a major
problem in a factory.
Sufficient Information
A case must have enough facts pertinent to the main issue to allow you to
draw evidence-backed conclusions about it. Too little information leads to
guesses, which aren’t educationally useful because there is no way to judge
their value. A case is very likely to include confl icting information, which
is consistent with real-world situations.
Cases can also include information that serves as noise to distract you
and makes it harder to distinguish useful information. If you’re new to the
case method, this can be hard to cope with. Textbooks and articles include
only information that is relevant to the main topic. Cases are different
because noise is a characteristic of real situations. Today, we are awash in
information, and cases can provide invaluable practice in fi ltering information according to its relevance and value to an issue.
No Objective Conclusions
Cases describe situations about which people have differing opinions.
They don’t consist of information that is all neatly aligned with a specific

14ANALYZING CASES
conclusion. Characters in the case may express strong opinions, but you
need to consider their views alongside those of other characters and other
information in the case. You, the reader, have to decide on a conclusion,
as you do in real-life situations.
Nonlinear Organization
Cases seem to have a logical structure. They have an opening section, a
sequence of headings and subheadings, and a concluding section. They
often have exhibits that look like those in textbooks or articles. Headings
and subheadings seem to divide the case into sections just as textbooks or
articles do. Nevertheless, business cases are typically nonlinear, meaning
the content is not presented in the most logical way. Information on a
single topic is scattered among different sections in a case. Case exhibits
are often designed in a way that it makes it difficult to extract high-value
information. They can also have significant gaps in information.
TEXTBOOK VS. CASE
Because you’ve spent years reading textbooks, let’s compare them to see
how they differ. (See exhibit 2-A.) The comparison shows why you’re
going to have to adjust the way you’ve learned to read.
As you can see, textbooks and cases present radically different reading
tasks. The purpose of textbooks is the transfer of knowledge, including
the principles and conclusions that experts in a domain of knowledge
accept. The organization of a textbook is logical, starting from basic concepts and progressing to more advanced concepts. The main skill needed
for textbooks is memorization.

WHAT IS A CASE?15
Cases provide information and express no conclusions about that information. They are literally meaningless until a reader gives them meaning. As just noted, cases appear to be logically organized, but they aren’t.
Information about the same topic is often scattered throughout the case.
These case features mean that you can’t be a passive reader, gliding your
highlighter over chunks of text, even though you don’t know whether
they’re important. When you read a case for the first time, pulling a highlighter across the page may feel like you’re doing something, but it’s an
illusion.
With cases, you need to change how you read and, ultimately, how
you think. Cases are a jigsaw puzzle with the pieces arranged in a confusing pattern. You need to take the pieces and fit them into a pattern that
helps you understand the main issue and think about the optimal ways to
address it. You need to be comfortable with less than perfect information
and an irreducible level of uncertainty. You need to be able to fi lter the
noise of irrelevant or relatively unimportant information. You need to
focus on key tasks that allow you to put pieces together in a meaningful
pattern, which in turn will give you a better understanding of the main
issue and put you in a position to make impactful recommendations.
Based on twenty-five years of teaching students at Harvard Business
School and other institutions how to navigate and excel at case-based
learning, I’ve identified techniques for making meaning from cases:
• Recognizing the main issue in a case that needs solving and the
most efficient way to go about investigating it.
• Reading the case actively and efficiently to provide a basis for your
analysis of the case.
• Following a path of analysis to arrive at an evidence-backed conclusion about the main issue.

THE SKILLS YOU
NEED TO READ AND
ANALYZE A CASE
A
s mentioned in the last chapter, cases usually have a superficial
organization that doesn’t provide much direction for readers.
Related information is scattered across sections, and the section
headings don’t necessarily help you discern the relative importance of the
information they contain. The information dispersed throughout the case
and the data you will extrapolate from calculations and exhibits are the
puzzle pieces that need to be assembled into a pattern that has meaning.
There are thousands of published cases, and each is, in a sense, unique.
No case presents the same set of facts as any other case. But cases also have
similarities that can facilitate your study of them. Most cases illustrate one
of three core scenarios:
• The need to make a critical decision and potentially persuade other
characters in the case to accept it
• The need to perform an in-depth evaluation that lays out the pros
and cons or strengths and weaknesses of the subject of the case
• The need to perform a comprehensive problem diagnosis that identifies the root causes of a problem described in the case
It isn’t surprising that these core scenarios come up again and again
because cases are about what happens in the real world. In business, certain scenarios do occur repeatedly. To understand information, we have
to have a way of organizing it. Developing the skills to identify which of
three scenarios is at the core of a case solves one of the biggest problems of
studying a case: how to meaningfully organize the information in it. This
is the first skill for understanding cases and the foundation upon which
you will build the other skills.

The sections that follow illustrate the three core scenarios and explain
how to recognize them in the cases you read.
DECISIONS
Please read the first two paragraphs of “General Motors: Packard Electric
Division” on page 173 and then return to this page.
Did you notice the sentence in the second paragraph?
The Product, Process, and Reliability (PPR) committee, which had the
final responsibility for the new product development process, had asked
[David] Schramm for his analysis and recommendation as to whether
Packard Electric should commit to the RIM grommet for a 1992 model
year car.
Schramm, the main character of the case, must recommend a decision
about producing a newly designed part used in the assembly of automobiles. Business cases organized around an explicitly stated decision
are probably the most common type, which isn’t surprising considering
that a central function of organizations of all kinds is making decisions.
Organizations have to make decisions; otherwise, they would cease to
exist.
How to Recognize a Decision Scenario
Decision scenarios are generally easy to recognize because the decision is
stated, often in the first section. Don’t be surprised if the word “decision”
isn’t used. Note that it’s absent in the sentence from the “General Motors”
case. But if you know what you’re looking for, the phrase “whether Packard Electric should commit to the RIM grommet for a 1992 model year
car” tells you that the main character has to make a decision about the
RIM grommet (a newly designed part for automobiles) and present it to
the members of a committee.
One of the best ways to identify the core scenario of a case is to ask
yourself what the main character has to do—what his or her most important task is. In “General Motors,” Schramm has to figure out what the best
decision is. Another test is to ask what the major uncertainty in the case is.
For Schramm, it’s what to do about the RIM grommet.
Knowing that a case is about a decision means you can use a
simple framework for analyzing it, which will be presented in detail in
chapter 4.

THE SKILLS YOU NEED TO READ AND ANALYZE A CASE19
EVALUATIONS
A case with an evaluation core scenario portrays a situation in which a
deeper understanding of a person, division, company, country, strategy,
or policy is necessary before any critical decisions or actions can be taken.
Here is the second paragraph of a case:
[S]timulated by their success in introducing a new distribution channel for
flowers, Owades and her two key associates, Fran Wilson and Ann Lee,
were reassessing the firm’s long-term growth strategy. Was Calyx & Corolla
more a mail-order operation or should it compete directly against more
traditional outlets, such as retail florists, and wire services, such as Florists
Telegraph Delivery (FTD)? How fast did it have to grow to protect its
initial success? What would be the financial implications of various growth
strategies? How should its personal objectives and those of its investors and
employees influence the character and pace of growth? 1
The first sentence of the paragraph says that the three leaders of a flower
company are “reassessing” their existing long-term strategy—in other
words, they are evaluating it. How do you evaluate something? You start
with criteria, the standards appropriate for the subject and the situation.
The questions in the second half of the paragraph suggest criteria for the
evaluation. You will fi nd that evaluation cases often state criteria as questions somewhere in the case.
How to Recognize an Evaluation Scenario
Cases that require an evaluation can be harder to identify than decision cases. At the beginning of a case, be alert for the words “evaluation,” “reevaluation,” “evaluate,” or “reevaluate” and similar ones such as
“assess,” “reassess,” or “appraise.” An evaluation scenario always identifies
a specific subject—for example, the performance of a person or a strategy.
Let’s use the two tests mentioned in the previous section about decision
scenarios. The first is, What does the main character have to do? When
the main character has to make a judgment about the worth, value, performance, effectiveness, outcome, or consequences of something, the core
scenario is an evaluation. The leaders of Calyx & Corolla want to assess
the effectiveness and consequences of their long-term business strategy.
The second test is, What is the major uncertainty of the case? For
the leaders of Calyx & Corolla, it seems to be whether the long-term
strategy is the right fit for the business and its stakeholders and will have

20ANALYZING CASES
the desired consequences such as sustaining the business and yielding the
desired financial results. To determine the answers to these questions, the
leaders must evaluate the current strategy.
The following paragraph is from the first section of another case:
The president called the repudiation “a turning point” in the history of
Argentina and declared, “We will not pay our debt with the hunger and
thirst of the Argentine people.” International authorities on sovereign debt,
among them the rock star Bono, supported the actions of the president. (See
Exhibit 1.) The Institute of International Finance, a global association of
financial institutions, however, wrote that “lack of progress implementing
structural reforms and Argentina’s aggressive conduct in the process of the
debt exchange are certain to put the long-term economic prospects of the
country at great risk.”2
The president of Argentina has decided to refuse to repay a large share
(65 percent) of its foreign debt. The decision is controversial, with the
president, Bono (!), and unnamed experts in favor, while an international
organization of financial companies, a trade group of banks and financial institutions, foresees economic disaster for the country. The unstated
question is: Which side is right? Your task is to evaluate the debt decision
to see whether the president was right to make it.
You can also ask, What is the major uncertainty of the case? The answer
is the impact on Argentina. The president’s refusal to pay the country’s
debts has to be evaluated to fi nd out whether it will help or hinder the
country— or both. The last possibility—that both could be true—is a
characteristic of evaluations. They almost always yield both positive and
negative findings. In the real world, the subject of an assessment is rarely
perfectly good or perfectly bad.
Like decisions, you can use a framework to guide the evaluation that
the case calls for. See chapter 5 for more details on evaluation analysis.
PROBLEM DIAGNOSES
We have all been the subject of a problem diagnosis. When you’re sick
and go to the doctor, your symptoms are a “problem” the doctor solves
by making a diagnosis of what is causing them and prescribing treatment
consistent with the diagnosis. Problem diagnosis is used in many disciplines, from business to engineering. Problem diagnosis simply means that
a significant problem needs a causal explanation. A problem can be an
outcome, reaction, result, or event. An example of an outcome or result
would be a company’s failed attempt to seed social responsibility initiatives

THE SKILLS YOU NEED TO READ AND ANALYZE A CASE21
in all of its divisions. The failure is a problem because the initiative is a
high priority for the company and no one knows why it didn’t work. The
purpose of the diagnosis is to find out why it didn’t work.
A problem can be positive or negative. An unexpected surge in sales is
a positive, but a business that doesn’t understand the reasons for the surge
may not be able to sustain it. Problems are also negative, for example, the
company’s failed social responsibility initiative.
Here is the first paragraph of a case about an innovative steel company:
Nucor Corporation had recorded sales of $755 million and a net income
of $46 million in 1986. It derived 99% of its sales and operating income
from steel making and fabrication at 10 sites around the United States. Its
steel-making capacity of 2.1 million tons made it the second largest domestic
mini mill. Its sales and profits had grown very rapidly in the 1970s but had
experienced some pressure in the 1980s, and had actually declined in 1986.
In order to get a better handle on these performance pressures, F. Kenneth
Iverson, Nucor’s chairman and chief executive officer (CEO), reviewed
the state of competition in the U.S. steel industry in general and Nucor’s
position within it in particular.3
The CEO of Nucor wants to understand the causes for the decline in
sales. If he knows what they are, he and his company may be able to make
changes that restore growth.
A good example of the efficacy of problem diagnosis is a US government agency charged with a very important mission: saving lives. Every
commercial aviation crash involving US carriers is investigated by the
National Transportation Safety Board (NTSB). Their goal is to understand the causes of the crash and then recommend changes that can prevent another one like it. These causal investigations and actions based on
them have contributed to a decrease in commercial airline accidents and
fatalities every decade since 1950. In 2017 there were no commercial passenger jet fatalities, the safest year on record.
How to Recognize a Problem-Diagnosis Scenario
Identifying problem-diagnosis cases can be difficult. They usually don’t
use the words “problem” or “diagnosis.” As you gain experience with
cases, you’ll recognize those in which the main character doesn’t know
why something has happened and needs to understand the why. As in the
Nucor example, a problem-diagnosis case will often open with an overview of the problem and introduce the main character who has to figure
out what the causes are.

22ANALYZING CASES
Again, let’s use the same two tests that have been applied to decision
and evaluation scenario cases: What does the main character have to do?
What is the major uncertainty of the case?
Here are two paragraphs from the opening of a case:
Tom Claflin, a member of NDL’s board and a venture capital backer of the
firm, offered his perspective:
All the venture capitalists believe in the company, and in Jock and Rob.
Yet this is their fourth time back to the well for capital, when the
money raised in each of the previous rounds was supposed to have
been suffi cient. Before the venture group puts in another $1 million or
$1.5 million, we must address the key issue: is it just taking longer to
prime the pump than we expected or is there something fundamentally
wrong with the concept? 4
What does the main character have to do? Tom Clafl in has been asked
to provide more funding to a startup. He along with other investors
believes in the company and its founders, but one round of funding was
supposed to suffice. The problem is the startup’s slow progress, and as a
prudent investor, Clafl in seeks to diagnose the cause or causes. Only then
can he make an informed decision about providing more funding.
What is the major uncertainty of the case? Clafl in doesn’t know why
the startup is taking longer than expected to succeed. He must understand
what the causes are and specifically whether they are normal growing
pains or fundamental flaws.
Chapter 6 has a detailed discussion of analyzing cases with problemdiagnosis scenarios.
READING A CASE BY ASKING QUESTIONS
Now you know the three core scenarios you’ll encounter in cases and
how to identify them. Your next step is to integrate this knowledge with
a reading process tailored to cases.
In contrast to a textbook, a case requires an active reader. You can’t sit
back and expect the case to tell you what you need to know. You have to
examine and rearrange its puzzle pieces, looking for a meaningful pattern.
The process is similar to a research project. You wouldn’t gather and read
all of the possible sources. You would look for sources on specific aspects
of the issue you’re researching, sort them into categories, read them to
determine their relevance, and if they are relevant, capture the information. It can be useful to think of a case as a type of research project.

For the exclusive use of Z. Wang, 2024.
THE SKILLS YOU NEED TO READ AND ANALYZE A CASE23
Remember that cases don’t tell you what they mean; they don’t provide
clear-cut answers. You have to be an active reader in order to find answers
that make sense to you; “active reader” means that you ask questions and
look for answers in the case.
Here is a series of eight questions for investigating a case that integrate
the core scenarios discussed earlier in this chapter. Eight may seem to be
an impractical number, but the first five can be accomplished quickly,
especially after you have used them a few times. You should consider how
much time an undirected reading and analysis of a case takes. Reading,
highlighting text without being sure whether the text is important, taking
notes without knowing whether they’re important, rereading, highlighting more text, and taking more notes—the random approach can take
hours and still be unproductive and therefore frustrating.
Many professors provide study questions for cases they assign for discussion, and sometimes students are confused about how to use them. Your
first option is to ask your professor whether you should prepare answers to
them. Typically, professors provide the questions as guides to important
issues in the case, but don’t expect you to prepare formal answers.
Case Reading Process
1. Read the first and last sections of the case. What do they tell you about
the core scenario of the case?
These sections typically give you the clues needed to identify the core
scenario.
2. Take a quick look at the other sections and the exhibits to determine
what information the case contains.
The purpose is to learn what information is in the case and where. Avoid
reading sections slowly and trying to memorize the content.
3. Stop! Now is the time to think rather than read. What is the core scenario
of the case? What does the main character have to do? What is the major
uncertainty?
Identify the core scenario by asking the two questions. Once you are
reasonably certain of the core scenario— decision, evaluation, or problem
diagnosis—you can use the relevant framework to ask the questions in the
next step. Those questions will give you a specific agenda for productively
exploring the case.

24ANALYZING CASES
4. What do you need to know to accomplish what the main character has
to do or to resolve the major uncertainty? List the things you need to know
about the situation. Don’t worry about being wrong.
This is probably the most important step of the entire process. If you don’t
know what you’re looking for in the case, you won’t find it. The right
core scenario framework will prompt you to list things that you need to
explore. For example, for a decision scenario case, you should think about
the best criteria the main character can use to make the decision. To
determine criteria, think about quantitative and qualitative tools you’ve
learned that can help you.
5. Go through the case, skim sections, and mark places or takes notes
about where you find information that corresponds to the list of things you
need to know.
6. You’re ready for a deep dive into the case. Carefully read and analyze
the information you’ve identified that is relevant to the things you need to
know. As you proceed in your analysis, ask, How does what I’m learning
help me understand the main issue?
The most efficient and least confusing way to read and analyze is to peel the
onion—to study one issue at a time. For instance, let’s say that a decision has
financial and marketing criteria. Analyzing the financial issues separately
from marketing is far less confusing than trying to switch back and forth.
As your analysis moves from issue to issue, you may discover gaps in your
knowledge and have to add items to your list of what you need to know.
7. Your ultimate goal is to arrive at a position or conclusion about the case’s
main issue, backed by evidence from the case. Remember, there are usually
no objectively right answers to a case. The best answer is the one with the
strongest evidence backing it.
As you learn more, ask, How does what I know help me understand the
main issue? When you are preparing a case for class discussion, consider
alternative positions. Finally, take some time to think about actions that
support your position.
8. What actions does your position support or require?
In the real world, analysis is often followed by action. A decision obviously
has to be implemented. Usually the entire point of a problem diagnosis is

THE SKILLS YOU NEED TO READ AND ANALYZE A CASE25
to target action that will solve the problem. And even evaluation has an
important action component: sustaining the strengths and shoring up the
weaknesses that it has revealed.
ANALYZING A CASE EFFECTIVELY
When you analyze a case, what do you actually do? “Analysis” is a word
with multiple meanings. In case study, analysis is the close examination
of the pieces of information in the case that you think may illuminate the
main issue. The case reading process and the identification of a case’s core
scenario provide the initial purpose for your analysis.
The purpose will shift as you go deeper into a case. Here’s an example:
Purpose: Determine the core scenario: it’s a decision.
Purpose: Find the decision options.
Purpose: List criteria that might be useful in making the
decision.
Purpose: Find evidence having to do with your criteria.
Purpose: Analyze the evidence related to the criteria.
Purpose: Determine the decision option that is most
strongly supported by the evidence.
Think of a research project again. As you proceed, your focus becomes
narrower, but— and this is important—you don’t lose sight of the project’s
goal. The goal of case analysis is to investigate the pieces of the puzzle
and arrange them into a picture of the main issue that makes sense to you.
The outcome of analysis is information, inferences, and calculations
sufficient to allow you to take a position on the main issue. Analysis should
be methodical and focused. Hit-or-miss analysis will be too scattered to
advance your understanding.
Following a Path of Analysis
All the fine generalizations in the previous paragraph need an example to
make them real. We’ll follow a case analysis for a few steps.
During a downturn, a furniture manufacturer sells its products to
retailers on credit, and they repay the loans monthly. The opening of
the case tells us that a credit manager for the manufacturer must decide
whether to continue to extend credit to two retailers, both longtime customers. The retailers are well behind in their loan repayments.

26ANALYZING CASES
First, think about what the credit manager needs to know to make the
decision. The retailers’ financial health certainly seems relevant. So is the
size of the local market and the firms’ operational performance (sales, cost
of goods sold, and related information). All three of these things could
become criteria for the manager’s decision.
You’re ready to conduct your analysis because you have criteria for making the decision. You inventory the case for information related to the
three possible criteria and find no information about the size of the local
market but some about sales over the last three years. Retailer A has had
declining sales until the most recent year and increasing cost of goods sold.
The economy of the country in which the retailer operates has been in
recession but has returned to growth in the last year. In the latest year for
which figures are available, retailer A has had a slight increase in sales. You
can infer that the recent trend toward a higher cost of goods sold is the
result of retailer A selling furniture at a discount, which is an understandable response to lagging sales and a way to clear old inventory. For retailer
A, you can say that the sales trend is slightly positive and supports a decision
to extend more credit, although possibly with conditions or limitations.
The findings based on one criterion aren’t reliable enough to make
a decision. You need to understand the financial health of the retailers.
Included in the case are three years of balance sheets and income statements. At this point, you have more analytical choices to make. There are
many metrics that will help you assess the financial health of a company.
Numbers expressing liquidity and capital structure can be computed from
the balance sheets and income statements, and both are important indicators of financial health. How do you measure them? The quick ratio and
the debt-to-equity ratio do that.
Here is a summary of the path of the analysis:
Decision: extend more credit to retailers A and B?
Criterion: Financial health
Metrics for assessing financial health?
Liquidity, Retailer A
Quick ratio calculated from exhibit: .076
Capital structure, Retailer A
Debt-to-assets ratio calculated from exhibit: 46%
Following this path, you learn something about retailer A. Its quick
ratio is below 1, meaning it may not have enough assets to pay off its

THE SKILLS YOU NEED TO READ AND ANALYZE A CASE27
liabilities in the short term. On the other hand, its debt-to-assets ratio is
a healthy 46 percent, meaning it has plenty of capacity to take on debt to
cover expenses if necessary. Although you need to know more to make a
decision about extending more credit to retailer A, you have started to fit
the puzzle pieces together that will eventually allow you to take a position
on the credit decision.
About Evidence
Evidence is a term that’s used often in this book. When you analyze a case,
evidence is information that supports a position on the main issue. The
main issue is defined by the case’s core scenario: a decision, an evaluation,
or a problem diagnosis. When you express a position about a decision,
evidence is the information you offer to justify the decision. The same is
true of evaluations and problem diagnoses.
Case evidence consists of facts, including numbers; calculations based
on factual numbers and reasonable assumptions; inferences from facts; and
statements by characters in the case. Evidence has a characteristic that’s
crucial to the credibility of a position or conclusion you advocate: it can
be independently verified. In case studies, that means your peers and professor can check your evidence against the content of the case.
Some evidence is more inherently reliable than other forms. Appropriate and correct calculations from well-vetted numbers are the gold standard of evidence. Statements by individuals in a case have to be regarded
as expressions of opinion, not truth. Personal opinion, even from an
expert, gains power to the degree that other evidence correlates with
it. A CEO could emphatically state positive views about her company’s
strategy, but her views gain authority when evidence from other sources
supports them.
About Numbers
Numbers, either stated as facts in the case or calculated from numbers
provided in the case, are one of the most powerful types of information
and evidence in cases. They are also among the most treacherous because
they can absorb an enormous share of your attention without providing
much clarity. When a case has a lot of quantitative information, the temptation is to begin with it, trying to understand what the numbers mean or
performing calculations. That is usually a mistake.5 Remember the point
made in the reading process section: if you don’t know what you’re looking for, you won’t find it.

28ANALYZING CASES
The critical question of the reading process is, What do I need to know
to accomplish what the main character has to do or to resolve the major
uncertainty? We just traced part of the path of analysis through the case
that dealt with the credit manager’s dilemma. Did you notice when the
calculations were made? They came at the end of the path:
Situation: decision ➞ possible criteria: fi nancial health ➞
metrics? ➞ liquidity and capital structure ➞ calculations
In business, numbers have meaning only in a specific context. Without
the context, they’re simply numbers. In the example, the liquidity and
capital structure ratios become meaningful only after we consider appropriate criteria for the specific decision and how to measure them.
And one number by itself generally doesn’t mean much. For the decision, the quick ratio and the debt-to-assets ratio need to be considered
together, along with the operational results. And even then, more calculations would make the picture of retailer A’s fi nancial health more precise.
For example, have there been any adverse changes in accounts receivable
versus accounts payable?
You’re now equipped with knowledge about the three core scenarios of
cases, a reading process, and analysis. In the next three chapters, you will
put this knowledge to work reading and analyzing complete cases.

CHAP TER 4
HOW TO ANALYZE
DECISION SCENARIO
CASES
T
he most common type of core scenario you’ll encounter in cases
is a decision. The first part of this chapter will define the unique
characteristics of a decision analysis and the second will walk you
through an analysis of a complete case, using the elements and the questions described in chapter 3.
The analysis of a decision scenario has six distinct elements:
• Identification of the required decision
• Review or identification of options
• Criteria selection
• Criteria-based analysis
• Recommended decision
• Proposed actions
Your professors probably will not discuss a decision scenario case by
asking questions about the six elements. They will have their own way of
facilitating the discussion. Nevertheless, the approach to analysis described
in this chapter will guide your exploration of a case and prepare you for
class discussion.
1. Identification of the Required Decision
Somewhere in the case, usually in the fi rst section, you’ll find a statement
of the decision that is needed. That tells you the case is built around a
decision scenario.
This document is authorized for use only by Zachary Wang in Int’l Bus Strategy IBM 4801-E01 (50293) SMR SESS 1 2024 taught by ERIC HUTCHINS, California

30ANALYZING CASES
2. Review or Identification of Options
Decisions usually have options. As soon as you know the case is about
a decision, look for the options. They might be binary—yes or no— or
there might be several competing possibilities and you need to know— or
define—what they are before you can analyze the case.
Here’s a suggestion for working on a case that has more than two
options. You can’t juggle three (or more) options in your mind. If you try,
you’ll become confused. Instead, first work on the two options that seem
most different from each other. Then work on the remaining options.
You should have an understanding of all the available options before you
make your final decision.
You may encounter decision scenarios in which the options aren’t
clearly defined. In these situations, you’ll need to define the most logical
options before beginning your analysis. Once you define them, you can
analyze which one is best.
3. Criteria Selection
The meaning of “criteria” may seem nebulous and abstract. Actually,
though, you use criteria all the time, even if you don’t call them by that
name. When you decide to buy a new cellphone, you have to have a way
to choose one. You might have a number of objective criteria: price, size
of the phone, screen resolution, quality of the camera, and size of internal
memory. Or you might care most about the appearance or social value of
the phone.
When studying cases, criteria are the answer to the following question:
What should I think about when making the decision? The criteria you
use are the most important part of analyzing a decision scenario. When
you don’t have any criteria in mind, you will roam around the case looking for something solid to hold onto. Irrelevant criteria will lead to wasted
time and leave you vulnerable to recommending a decision with little to
no supporting evidence.
Decision criteria should be:
• Relevant to the decision. They should reflect concepts that can help
you understand a specific decision. A case about a leader calls for
criteria relevant to leadership, not accounting or marketing.
• Relevant to the case evidence. There are many possible criteria for a
given decision, but you need to look for those that reflect the evidence in the case. Early in your study of a case, you’ll need to make
some educated guesses about the criteria. (See the analysis of the

HOW TO ANALYZE DECISION SCENARIO CASES31
case in the second part of this chapter for more explanation of this.)
Technical concepts and metrics appropriate to the decision can assist
you in picking criteria. For example, take a case that revolves around
an accounting decision. You would want to consider which of the
accounting concepts you’ve learned could serve as possible criteria.
• Limited to the minimum necessary for making a sound decision. A decision recommendation is difficult when many criteria are used. You
are forced to work with and reconcile the findings generated by
many factors. Your task will be to identify the top criteria—that is,
those that are most helpful in revealing what you need to know for
making the decision.
4. Criteria-Based Analysis
The analysis of a decision directed by criteria examines the case evidence
related to each criterion and what it says about the available options. Your
goal is to learn which option offers the best fit between the criteria and
the evidence in the case.
5. Recommended Decision
Once you have findings on all of your criteria, take a step back and see
what decision recommendation they seem to support most strongly. Findings on different criteria often confl ict with each other, requiring you to
make a judgment of which criteria and what evidence are most important
for making the decision.
6. Proposed Actions
A decision is only as good as its implementation. A smart decision can be
undermined by poor implementation. For that reason, take action planning seriously. It’s a skill every bit as important as decision making. The
purpose of a decision action plan is to implement the decision as effectively as possible.
