Degree of Problem Definition
Exploratory Research
(Unaware of Problem)
“Our sales are declining and
we don’t know why.”
“Would people be interested
in our new product idea?”
Descriptive Research
(Aware of Problem)
Causal Research
(Problem Clearly Defined)
“What kind of people are buying “Will buyers purchase more of
our product? Who buys our
our products in a new package?
competitor’s product?”
“Which of two advertising
“What features do buyers prefer campaigns is more effective?”
in our product?”
Exploratory Research
Secondary data
Experience survey
Pilot studies
Exploratory Research
• Initial research conducted to clarify and
define the nature of a problem
• Does not provide conclusive evidence
• Subsequent research expected
Descriptive Research
• Describes characteristics of a population or
phenomenon
• Some understanding of the nature of the
problem
I keep six honest serving men, (they
taught me all I knew), their names are
what, and why, and when, and how,
and where and who.”
--Rudyard Kipling
Descriptive Research Example
•
•
•
•
•
Weight Watchers average customer
Woman about 40 years old
Household income of about $50,000
At least some college education
Trying to juggle children and a job
Descriptive Research Example
•
•
•
•
Men’s fragrance market
1/3 size of women’s fragrance market
But growing at a faster pace
Women buy 80 % of men’s fragrances
Causal Research
• Conducted to identify cause and effect
relationships
Identifying Causality
• A causal relationship is impossible to prove.
• Evidence of causality:
– 1. The appropriate causal order of events
– 2. Concomitant variation--two phenomena
vary together
– 3. An absence of alternative plausible
explanations

Research Stages
• Cyclical process - conclusions generate new
ideas
• Stages can overlap chronologically
• Stages are functionally interrelated
– Forward linkages
– Backward linkages

First step
Problem, opportunity, or monitor operations
Discovery before definition
Problem means management problem
“The formulation of the problem
is often more essential than its
solution”

Exploratory Research Techniques
Two Examples
• Secondary data (historical data)
– Previously collected
– Census of population
– Literature survey
• Pilot study
– A number of diverse techniques
Focus Group Interview
Research Design
• Master plan
• Framework for action
• Specifies methods and procedures
Basic Research Methods

•
•
Surveys
Experiments
Secondary data
Observation
Selecting a Sample
Sample: subset
of a larger population.
SAMPLE
POPULATION
Sampling
• Who is to be sampled?
• How large a sample?
• How will sample units be selected?
Data Gathering Stage
Data Processing and Analysis
Conclusions And Report Writing
• Effective communication of the research
findings
Research Proposal
• A written statement of the research design
that includes a statement explaining the
purpose of the study.
• Detailed outline of procedures associated
with a particular methodology
