Matrix Diagram Decision Making

What is a Decision Matrix?

Decision matrix: a decision-support tool allowing
decision makers to solve their problem by evaluating,
rating, and comparing different alternatives on multiple criteria.

Five types of matrix diagrams exist: C, L, T, X, and Y matrix
diagrams. The name of each is denoted by a letter resembling the
shape of the matrix the diagram produces; most common are L and
T matrices. Matrix diagrams are used to explore the relationships
between data sets to identify trends, isolate potential problems,
and improve performance.
