1, 3, 9 Relationship Values are Better

The preferred, traditional QFD numerical scores are:

NONE = 0

WEAK = 1

MODERATE = 3

STRONG = 9

This philosophy demands that you feel a “STRONG” relationship is 3 times more valuable than a “MODERATE” and 9 times more valuable than a “WEAK”.

The 0, 1, 3, 9 philosophy will illuminate those “HOW”s that strongly satisfy “WHAT”s. This is the scoring philosophy Boeing STL has successfully employed, and it is also the accepted QFD standard. This philosophy was used when scoring the three FWV QFD matrices.
