When and Why?

The consequent use of the list of functional requirements with functions on the top hierarchy levels and CTQs as sub items of functions already defines relations between CTQs and functions. By using the copy link mechanism, even n to m relations can be handled. Functions can be prioritized by simply summing up priorities of the subitem CTQs. All this makes use of a QFD 2 matrix obsolete.

Use the QFD 2 matrix only if you do not want to sort CTQs under functions or you have many relations from CTQs to different functions.
