3.6 MATRIX DIAGRAM
The matrix diagram is similar in concept to quality function deployment (QFD) in its
use of symbols, its layout, and its application.
Like other N7 tools, the matrix diagram is a brainstorming tool that can be used in a
group to show the relationships between ideas or issues. Matrix diagrams are simple
to use and can be used in two, three, or four dimensions.
For our purposes, we provide an example of a simple two-dimensional matrix in
Figure 3.8.
Figure 3.8 Matrix Diagram
The steps are as follows:
Determine the number of issues or dimensions to be used in the matrix.
Choose the appropriate matrix.
Place the appropriate symbols in the matrix.
Figure 3.9 shows a responsibility matrix diagram. The legend at the bottom of the
figure shows the extent of responsibility among the different people. This grid in
Figure 3.9 gives a simplified version of the QFD.
