A basic decision matrix consists of establishing a set of criteria and a group of potential candidate designs.
The number of times "better" and "worse" appeared for each design is then displayed, but not summed up.
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.
[2] The advantage of the decision-making matrix is that it encourages self-reflection amongst the members of a design team to analyze each candidate with a minimized bias (for team members can be biased towards certain designs, such as their own).
However, there are some important disadvantages of the decision-matrix method: Morphological analysis is another form of a decision matrix employing a multi-dimensional configuration space linked by way of logical relationships.
