, Lecture 1 – Introduction
Managerial decisions that are based on the results of “good” research tend to be more
effective. On the other hand, hunches, intuition, and past experiences are more likely
to be wrong.
Experience without research leads to losses.
Why should future managers know about research?
o To be able to perform business research
Undertake research yourself to solve the smaller problems you
encounter.
o To be able to steer business research
Interact effectively with researchers/research agencies
o To be able to evaluate business research
To discriminate between good and bad research proposals of
researchers/research agencies.
To discriminate between good and bad published research studies.
Business research is a series of well-thought-out and carefully executed activities that
enable the manager to know how organisational problems can be solved, or at least
considerably minimised.
A business researcher:
o Specifies the information necessary to address these issues
o Designs the method for collecting information
o Manages and implements the data collection process
o Analyses the results
o Communicates the findings and their implications.
Hallmarks of scientific research
o Purposiveness – know the “why” of your research
o Rigor – ensuring a sound theoretical base and methodological design
o Testability – being able to test logically developed ideas based on data
o Replicability – finding the same results if the research is repeated in similar
circumstances
o Precision & Confidence – drawing accurate conclusions with a high degree of
confidence
o Objectivity – drawing conclusions based on facts (rather than on subjective
ideas)
o Generalisability – being able to apply research findings in a wide variety of
different settings
o Parsimony – shaving away unnecessary details, explaining a lot with a little
