Focused Improvement

The point is that P-M Analysis is not just another improvement tool; it is an entirely new way of examining and interpreting a situation.

The analysis is thus applied to a limited group of possible causes, while others are left out of the picture.

The fact that a quality defect is occurring means either that some of the causal factors that should be controlled have been overlooked, or that there are deficiencies in some of the causal factors that are being controlled.

When faced with a problem, we always seem to assume that there must be a definite cause and focus our efforts on finding it.
