Notes

The Matrix Data Analysis Chart is one of the second seven tools according to Mizuno, although others replaces it with the Prioritization Matrix. It is often abbreviated to MDAC.

The complexity of the statistical method normally associated with this diagram (Principal Component Analysis) has led to other books not discussing MDAC and offering an alternative 'seventh' tool. It is included here not just for completeness, but because practical use can still be made of it.
