Review, analysis and classification of the literature on QFD - Types of research, difficulties and benefits

This paper presents a review, analysis, classification and codification of the literature on quality function deployment (QFD) produced between 2002 and 2006. The publications were classified into two main groups: conceptual research and empirical research. The studies focused more on quality matrix problem solving and the main difficulties are reported. However, few studies have been done on solutions for other important aspects. Further research is needed on how to reduce the difficulties of using QFD. (C) 2008 Elsevier B.V. All rights reserved.
