This Relationships Matrix Diagram is a management tool for analyzing and determining the relationship of data sets. Professionals and project managers are responsible for many projects, deals, and clients. These projects are influenced by a variety of factors that determine their trajectory. The matrix diagram assists project managers in visualizing these complex equations and relationships. This diagram is a table that allows for the analysis of data sets to make better decisions. It exemplifies the nature and intensity of the association between two or more groups of objects. The relationship is then represented in each cell by either a number or a symbol, depending on where the two elements intersect in the matrix.
