The **decision-matrix method**, also **Pugh method**, is a quantitative 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 investments options, vendor options, product options or any other set of multidimensional entities.

A basic decision matrix consists of establishing a set of weighted criteria upon which the potential options can be decomposed, scored, and summed to gain a total score which can then be ranked.

Morphological analysis is another form of a **decision matrix** employing a multi-dimensional configuration space linked by way of logical relationships.
