QFD math is simple and easy!
To compute a relative priority simply multiply the array of “WHAT” weights with the array of any “HOW” scores and sum these products.
For ease of interpretation the raw scores are usually scaled to 100. In the example, the raw score of 93 represents 61% of the total output emphasis.
This non-FWV example also illustrates the importance of the word relative. The computed priorities are only relative to the group of potential solution options (“HOWs”) that were scored against the objectives (“WHATs”). If a solution option is missing, the computed priorities will not change but the scaled priority may be different once that omission is corrected. The relative priority of one solution over another is an important QFD output concept.
