Decision Matrix
Also called: Pugh matrix, decision grid, selection matrix or grid, problem matrix, problem
selection matrix, opportunity analysis, solution matrix, criteria rating form, criteriabased matrix.
Description
A decision matrix evaluates and prioritizes a list of options. The team first establishes a list of
weighted criteria and then evaluates each option against those criteria. This is a variation of the
Lshaped matrix.
When to Use a Decision Matrix
When a list of options must be narrowed to one choice.
When the decision must be made on the basis of several criteria.
After the list of options has been reduced to a manageable number by list reduction.
Typical situations are:
When one improvement opportunity or problem must be selected to work on.
When only one solution or problemsolving approach can be implemented.
When only one new product can be developed.
Decision Matrix Procedure
1.
Brainstorm the evaluation criteria appropriate to the situation. If possible, involve
customers in this process.
2.
Discuss and refine the list of criteria. Identify any criteria that must be included and any
that must not be included. Reduce the list of criteria to those that the team believes are
most important. Tools such as list reduction and
multivoting
may be useful here.
3.
Assign a relative weight to each criterion, based on how important that criterion is to the
situation. Do this by distributing 10 points among the criteria. The assignment can be
done by discussion and consensus. Or each member can assign weights, then the numbers
for each criterion are added for a composite team weighting.
4.
Draw an Lshaped matrix. Write the criteria and their weights as labels along one edge
and the list of options along the other edge. Usually, whichever group has fewer items
occupies the vertical edge.
5.
Evaluate each choice against the criteria. There are three ways to do this:
Method 1: Establish a rating scale for each criterion. Some options are:
1, 2, 3:
1 = slight extent, 2 = some extent, 3 = great extent
1, 2, 3:
1 = low, 2 = medium, 3 = high
1, 2, 3, 4, 5:
1 = little to 5 = great
1, 4, 9:
1 = low, 4 = moderate, 9 = high
