means to actually apply the tools of analysis (such as five-forces analysis, value-chain analysis,
etc.).
In this part of the analysis, point out that it is important to test one’s assumptions about
Discussion Question 8: Why is it important to understand the assumptions that are being
used to make decisions and take action?
The SUPPLEMENT below presents Peter F. Drucker’s views about the critical
importance of making valid and informed assumptions in resolving the strategic issues that many
businesses face.
Extra Example: How Assumptions Drive the Theory—and Success—of a Business
Peter F. Drucker is a highly notable management expert whose books and articles on management have had an
enormous impact on modern management practices. In this article, Drucker describes how important it is for
businesses to understand the assumptions that underlie the actions they take.
“The root cause of nearly every [management crisis] is not that things are being done poorly. It is not even that the
wrong things are being done. Indeed, in most cases, the right things are being done—but fruitlessly. What accounts
for this apparent paradox? The assumptions on which the organization has been built and is being run no longer fit
reality. These are the assumptions that shape any organization’s behavior, dictate its decisions about what to do and
what not to do, and define what the organization considers meaningful results. These assumptions are about markets.
They are about identifying customers and competitors, their values and behavior. They are about technology and its
dynamics, about a company’s strengths and weaknesses. These assumptions are about what a company gets paid for.
They are what I call a company’s theory of the business.”
“It usually takes years of hard work, thinking and experimenting to reach a clear, consistent, and valid theory of the
business. Yet to be successful, every organization must work one out. What are the specifications of a valid theory of
the business? There are four:
1. The assumptions about environment, mission, and core competencies must fit reality.
2. The assumption in all three areas [in #1] have to fit one another.
3. The theory of the business must be known and understood throughout the organization.
4. The theory of the business has to be tested constantly.”
