“The formulation of the problem
is often more essential than its
solution.”
Albert Einstein
Problem Definition
• The indication of a specific business
decision area that will be clarified by
answering some research questions.

Ascertain the Decision Maker’s
Objectives
• Decision makers’ objectives
• Managerial goals expressed in measurable
terms.
8
The Iceberg Principle
• The principle indicating that the dangerous
part of many business problems is neither
visible to nor understood by managers.
Understand the Background of
the Problem
• Exercising judgment
• Situation analysis - The informal gathering
of background information to familiarize
researchers or managers with the decision
area.
10
Isolate and Identify the Problems,
Not the Symptoms
• Symptoms can be confusing
11
Symptoms Can Be Confusing
Twenty-year-old neighborhood swimming
association:
• Membership has been declining for years.
• New water park -residents prefer the
expensive water park????
• Demographic changes: Children have
grown up
Organization
Twenty-year-old
neighborhood
swimming
association in a
major city.
Symptoms
Membership has been
declining for years.
New water park with
wave pool and water
slides moved into
town a few years ago.
Problem Definition
Based on Symptom
True Problem
Neighborhood
residents prefer the
expensive water
park and have
negative image of
swimming pool.
Demographic changes:
Children in this 20year-old neighborhood
have grown up. Older
residents no longer
swim anywhere.

Problem definition
Progressive Abstraction Technique
1. Basic description of the problem
2. Gradually moving towards a higher level of abstraction
(until a usable definition has been reached)
- the problem is automatically extended, new definitions
may show up
- new definitions can be evaluated regarding applicability
- when a higher level of abstraction has been reached, it is
often easier to identify solutions
3. The decision maker/analyst is forced into a systematic
way of searching for substructures and relationships
Problem definition
Boundary examination technique
1. Purpose: to restructure the assumptions and to develop
new ways of looking at the problem
2. Procedure:
•describe the problem, as it looks at the moment
•identify key elements in the definition and examine them to
reveal underlying assumptions
•analyse each assumption and identify its causes and effects
•redefine the problem based on the deeper understanding of
the elements achieved during this process
•3. Advantages:
•provocative definition of the problem
•reveals limits which are difficult to identify
•stresses the need of a flexible definition of the problem
Problem definition
Interrogatories W’s+H
(who, what, where, when, why, how)
1. Purpose: To make sure that all aspects of the problem
has been considered
2. Procedure:
- construct questions for each of the 5 W’s+H
- answer the questions
- evaluate the proposed answers
- if an improvement shows up:
is it cost efficient?
if so change accordingly
Very efficient technique which can be applied in any phases
of the problem definition
Problem definition
Wishful thinking technique
1. Purpose: To isolate the process of defining the problem from
non-recognized but irrelevant alternative assumptions
2. Procedure:
- formulate questions, targets, situations or a problem
- accept that everything is possible
- use imagination to formulate statements like: “I would like to..”
or “If I could choose…”
- examine each statement and apply it as a stimuli
- return to reality and formulate statements like: “Even if I can’t do it,
then I can…”
- repeat the last three steps if needed
Problem definition
Brain storming
1. Purpose: To generate as many ideas as possible
2. Procedure:
- select a problem, which all participants have some knowledge/
experience about
- describe the problem in a neutral way
- write down all suggestions on a board, so everybody can see them
- evaluation must not start until all ideas have been mentioned
- try to force more ideas
- strive for as many ideas as possible so quality can be extracted from
quantity
- accept all ideas - even the most absurd
- stimulate associations and extensions of generated ideas
Determine the Unit of Analysis
• Individuals, households, organizations, etc.
• In many studies, the family rather than the
individual is the appropriate unit of
analysis.
23
Determine the Relevant Variable
• Anything that may assume different
numerical values
24
Types of Variables
•
•
•
•
Categorical
Continuous
Dependent
Independent
Hypothesis
• An unproven proposition
• A possible solution to a problem
• Guess

research objectives

Basic Questions Problem Definition
•
•
•
•
•
•
•
What is the purpose of the study?
How much is already known?
Is additional background information necessary?
What is to be measured? How?
Can the data be made available?
Should research be conducted?
Can a hypothesis be formulated?
Basic Questions Basic Research Design
• What types of questions need to be
answered?
• Are descriptive or causal findings required?
• What is the source of the data?
Basic Questions Basic Research Design
• Can objective answers be obtained by
asking people?
• How quickly is the information needed?
• How should survey questions be worded?
• How should experimental manipulations be
made?
