Quality function deployment (QFD) is the product development process to maximize customer satisfaction. The engineering design characteristics related to product performance are specified for this purpose. For dealing with the fuzzy nature in the product design processes, fuzzy approaches are applied to represent the relationships between customer requirements (CRs) and engineering design requi...

In this study, Turkish automotive sector needs for flexibility will be determined, and the relationships between flexibility levers and flexibility performance criteria will be evaluated with respect to the sectoral needs. The choice of the appropriate lever combinations will be made for the sector by using the results of this evaluation. The flexibility strategies will be ranked by using a fuz...

In this article an overview of the state of the art of QFD in software development or also called Software QFD is given. The differences between classic QFD in manufacturing industries and Software QFD are described. Following certain software specific QFD models (Zultner, Shindo, Ohmori, Herzwurm and Schockert), which can be considered as the most appreciated ones in theory as well as in pract...

What are the Best Practices of QFD? This was the driving question approx. a dozen experienced users of Quality Function Deployment (QFD) wanted to answer during various two-day workshops. The QFD Institute Germany e.V. (QFD-ID) had invited to come up for discussion on the Best Practices of QFD. The QFD-ID exists for almost 10 years now, but the origins of QFD and its successful application worl...

Online opinions provide informative customer requirements for product designers. However, the increasing volume of opinions make them hard to be digested entirely. It is expected to translate online opinions for designers automatically when they are launching a new product. In this research, an exploratory study is conducted, in which customer requirements in online reviews are manually transla...

Supplier selection is considered as one of the most critical issues encountered by operations and purchasing managers to sharpen the company’s competitive advantage. In this paper, a novel fuzzy multi-criteria group decision making approach integrating quality function deployment (QFD) and decision making trial and evaluation laboratory (DEMATEL) method is proposed for supplier selection. The p...

The case study will illustrate how QFD was used to develop a new.QUALITY FUNCTION DEPLOYMENT QFD: A CASE STUDY. quality function deployment in healthcare a literature review and case study Application of the technique will be provided in a case study. quality function deployment case study pdf The case study will illustra...

There are varieties of QFD combination forms available that can help management to choose the right model for his/her types of problem. The proposed MOCC-QFD-FMEA model is a right model to include variety of objectives as well as the risk factors into the model of the problem. Due to the fact that the model also takes into consideration the concept of Fuzzy set, it further allows management...

This paper presents a literature review of quality function deployment (QFD) based on a reference bank of about 650 QFD publications established through searching various sources. The origination and historical development of QFD, especially in Japan and the US, are briefly accounted first, followed by a partial list of QFD organizations, softwares, and online resources. Then a categorical anal...

Quantitative QFD (Q2FD) is an extension of conventional Quality Function Deployment (QFD). Q2FD incorporates quantitative requirements decomposition models into the QFD framework. It also rearranges conventional QFD matrices to facilitate quantitative capture and both forward and backward chaining of performance values. The rearranged matrices also allows full representation of QFD matrices wit...
