What Is It Good For?
|
|
This tool helps compare the efficiency and effectiveness
of alternatives based on the relationship between two criteria,
for example performance and cost. It also is a useful way to set
priorities, compare elements, or
spot outlying data or extreme areas.

How Do I Use It?
|
|
Create a matrix diagram by aligning two criteria,
one on each axis.
- Alternatives
- A matrix could be made in which needs and objectives are
aligned on one axis and the screened solutions are aligned on
the other. Balancing needs and objectives against possible solutions
would yield a variety of alternative combinations.
A cost-performance matrix, for example, would chart the
cost of an alternative on one axis and a measure of performance
on the other axis. Placing alternatives on this matrix would
show which alternatives provided the most effective performance
for the least cost. An alternative high in cost and performance
might be preferable to an alternative low in cost and performance.
-
- Problem areas
- By graphing elements on a matrix and shading in an acceptable
range, you can quickly find problem or extreme areas. Align
one need, objective, criteria, or other factor on one axis and
align a measurement on the other. Then place each alternative
on the chart.
