Decision Matrix Also called: Pugh matrix, decision grid, selection matrix or grid, problem matrix, problem selection matrix, opportunity analysis, solution matrix, criteria rating form, criteria-based 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 L-shaped 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 problem-solving 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 L-shaped 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

Make sure that your rating scales are consistent. Word your criteria and set the scales so that the high end of the scale (5 or 3) is always the rating that would tend to make you select that option:
