Matrix

A matrix compactly displays the interrelationship between two or more datum. Many business professions use matrices. Auditors develop them to identify the relationships between threats and controls. Systems analysts develop them to identify the relationship between inputs and outputs for a computing system. You can use them, too, for many purposes, especially to display relationships in a compact chart.

Matrices offer several advantages. They enable displaying a large amount of information in a compact form. They are also easy to prepare and show relationships among pieces of information. Finally, they provide a good basis for making decisions.
