This is a T-type matrix diagram. This matrix is a combination of two L-type matrices joined by a single list i.e, compares the two data sets with one main list. There are three groups of items where group A is related to both group B and group C. But group B is not connected to group C. This matrix chart is used to analyze the relationship between three factors with direct or indirect relationships. In this example, a T-type matrix diagram is used for comparing the individual skills on different project and project execution performances.
