Invented by [[Stuart Pugh]] theThe '''decision-matrix method''', also '''Pugh method''', or '''Pugh Concept Selection''', invented by [[Stuart Pugh]], is a qualitative technique used to rank the multi-dimensional options of an option set. It is frequently used in [[engineering]] for making design decisions but can also be used to rank investment options, vendor options, product options or any other set of multidimensional entities.

A basic [[decision matrix]] consists of establishing a set of criteria options which are scored and summed to gain a total score which can then be ranked. Importantly, it is not weighted to allow a quick selection process.

A weighted decision matrix operates in the same way as the basic decision matrix but introduces the concept of weighting the criteria in order of importance. The resultant scores better reflect the importance to the decision maker of the criteria involved. The more important the criteria the higher the weighting it should be given. Each of the potential options are scored and also multiplied by the weighting given to each of the criteria in order to produce a result.

The advantage of the decision making matrix is that subjective opinions about one alternative versus another can be made more objective. Another advantage of this method is that sensitivity studies can be performed. An example of this might be to see how much your opinion would have to change in order for a lower ranked alternative to out rank a competing alternative.

[[Morphological analysis (problem-solving)|Morphological analysis]] is another form of a '''decision matrix''' employing a multi-dimensional configuration space linked by way of logical relationships.
