Amihud Hari, Joseph Eli Kasser, Menachem P. Weiss · INCOSE International Symposium · 2006
Abstract Quality Function Deployment (QFD) has been used to elucidate and negotiate requirements for at least 20 years. QFD has a lot to offer but when used to specify complex systems, has been found to have a number of deficiencies, has been perceived as a time consuming process and has been found as being difficult to apply to complex systems. This paper summarizes the top five lessons learned from 15 years of experience in using QFD in the elicitation, elucidation and negotiation of requirements for complex systems.
