This technique is alternatively referred to as the decision matrix, evaluation matrix, or weighted criteria matrix. However, regardless of the nomenclature, its purpose remains identical, to select one option from a range of alternatives based on a set of criteria. In order to accomplish this, the technique visualises the decision in a matrix. The criteria used in the evaluation are each individually given weights and each alternative is scored for each of the criteria. By multiplying the scores by the assigned weight and adding the weighted scores for each alternative, the solution that is most valued can be determined.
