This is a C-shaped matrix diagram. This matrix compares and analyses three sets of data of different lists. A C-shaped matrix chart is not a circular flow but a three-dimensional cube diagram. When three types of lists have to be analyzed simultaneously, a C-type matrix chart is the usual go-to. The roof-shaped matrix is used with an L- or T-shaped matrix to show one group of items relating to itself. It is most commonly used with a House of Quality, where it forms the "roof" of the "house." In the example, the customer requirements are related to one another. For example, a strong relationship links Purity and Water, while Viscosity is unrelated to any of the other requirements.
