1 Introduction to Quantitative Analysis

Interviews, statistical
sampling, and company reports provide input data for quantitative analysis

2) In the early 1900s, Henry Ford
pioneered the principles of the scientific approach to management.

3) Managers do not need to be familiar
with the limitations, assumptions, and/or specific applicability of the
quantitative analysis technique to use it for accurate decision making.

4) During World War II, many new
scientific and quantitative techniques were developed to assist the military,
and these developments were so successful that many companies started using
similar techniques in managerial decision making and planning after the war.

5) When a problem is difficult to
quantify, it may be necessary to develop unspecific objectives.

6) The Quantitative Analysis Approach
consists of six steps.

7) A mathematical model shows the
relationship between quantifiable and non-quantifiable information.

8) Decision variables may also be called
9) Model variables can be controllable or
10) A series of steps or procedures that
are repeated is known as an algorithm.

11) A model is a representation of a

12) A parameter is a measurable quantity
that may vary or is subject to change.

13) Trying various approaches and picking
the one resulting in the best decision is called incomplete enumeration.

14) All problems can be solved by
considering only the quantitative issues.

15) A profit equation is an example of a
schematic model.

16) Testing the data and model should be
done before the results have been analyzed.
17) Sensitivity analysis helps us estimate
the effect of known and unknown errors in our model.
18) Models can help us analyze a problem
and sell a decision to those who must implement it.

19) A sensitivity analysis allows a
manager to answer the “what if” questions.

20) One problem in using a quantitative
model is that the necessary data may be unavailable.
