This is an architecture matrix diagram for engineering. A matrix diagram is a table that enables comparison across sets of data so that better decisions can be made. It illustrates the existence and significance of the connections between the items in pairs from two or more sets. Each cell where the two elements intersect in the matrix will then have a number or symbol indicating the relationship between them. A matrix diagram can be incorporated with other tools for making decisions. On EdrawMax, you can find and create more matrix diagrams.
