Using alternatives, criteria and weights to decide.
The Decision Matrix is a technique making use of alternatives, criteria and possible criteria weights. Criteria weights can be determined by intuition and paired comparison.
Have a list of alternatives and criteria complete.
Assign weights to these criteria, either on intuition or using a technique.
Once alternatives, criteria and weights are listed, each alternative can be scored for each criteria.
All the scores for each criteria can be computed to get a total score for each alternative.
You can also execute this matrix without weighted criteria. If you are using weights, you can decide to distribute a limited number of points over the criteria or compare criteria pairwise.
