Abstract: At first, two questions in the process of applying Quality Function Deployment(QFD) method are analyzed. Then, according to these questions, restructuring House of Quality(HoQ) using principal factor analysis is presented. In the HoQ which was restructured, the relationship between product quality characters is terminated and the HoQ is easy to be decomposed into smaller HoQ. So the scale of HoQs after this stage can be decreased. Finally, it''s application in service is presented.

Key words: House of Quality, principal factor analysis, restructuring, correlation matrix
