![]() Because matrix diagrams help you analyze data, they are also extensively used in the Measure and Analyze phases of the DMAIC methodology. If there is no relationship, then it is left blank. Symbols indicating the strength of the relationships are then entered in the cell where the row and column of the two elements intersect. The elements in different groups are placed in rows and columns and relationships among them are analyzed by the team. Roof-shaped relates one set of elements to itself.Ī matrix diagram, also called a matrix chart, is a management and planning tool used for identifying relationships between two to four groups of elements or among elements in a single group.X-shaped relates four sets of elements.C-shaped relates three sets of elements simultaneously.Y-shaped Relates three sets of elements where one set is related to the other two sets in a circular manner. ![]() ![]() T-shaped Relates three sets of elements where there is no relation between the two sets that are related to a common set.L-shaped Relates two sets of elements to one another or a single set of elements to itself.Matrix diagrams can be sorted into several types depending on the number of data sets being compared. It can be formed by bending the columns of sets A and B in the T-matrix in such a way that there is an interrelation between the elements of these two sets. The Y-shaped matrixis a matrix diagram that relates three sets of elements where one set is related to the other two sets in a circular manner.
