Quality function deployment (QFD) is a customer-driven quality management and product development system for achieving higher customer satisfaction. The QFD process involves various inputs in the form of linguistic data, e.g., human perception, judgment, and evaluation on importance or relationship strength. Such data are usually ambiguous and uncertain. An aim of this paper is to examine the i...

Quality function deployment (QFD) is a widely-used methodology for developing a design quality aimed at satisfying the customer and translating the customer’s demand into design targets. As QFD methodology is based on the voices of customers, it requires a group of individuals, or decision makers (DMs), to express their preferences. However, there can be a bottleneck since DMs may not have a pe...

An investigation is described into the application of quality function deployment (QFD) and case based reasoning (CBR) to software quality assessment. It is believed that the integration of CBR and QFD may be an effective means of supporting the development of quality software. The main aim in the research is to develop a CBR oriented software quality advisor to support the attainment of qualit...

In the rapid technological innovation and changes era, the key to the survival company is the continuous improvement of its process. In this paper, we introduce Software Process Improvement (SPI) and Quality Function Deployment (QFD); and for combining also the staged model and the continuous model in CMMI, the Software Process Improvement framework with CMMI has two parts: 1) Software Process ...

Six Sigma is a popular management strategy for the shop floor. Can it be applied to software? Software development is knowledge acquisition – it is different from industrial engineering. This paper explains the mathematical foundations for statistical thinking when lack of data samples prevents the use of proper statistics. The approach is based on Deming’s process chains and Akao’s Quality Fun...

A structured method is called quality function deployment (QFD) that translates the voice of the customer into both of the product and service development. The architecture of QFD is composed of a set of matrices that is often referred to as the house of quality (HOQ). HOQ is regarded as a part of the QFD process. The matrices of HOQ include the importance of customer requirements and the relat...

Traditional QFD planning method compromises contradictions between engineering characteristics to achieve higher customer satisfaction. However, this compromise trade-off can not eliminate the contradictions existing among the engineering characteristics which limited the overall customer satisfaction. QFD (Quality function deployment) integrated with TRIZ (the Russian acronym of the Theory of ...

This paper presents the concepts and principles of Quality Function Deployment (QFD) as they have been implemented by Ford company. The paper illustrates the essential linkages between external & internal customers to suppliers (i.e., 'Voice-Quality-Satisfaction' Chains). It discusses the various arguments and proposals that link together the end user customers voice to the internal customer-su...

Quality function deployment (QFD) is applied to university education system in this paper. It discusses in detail the various aspects and tools associated with QFD. Now a day’s employment competition is fiercer because of global economic crisis. So how to design education program for improving undergraduate competitiveness is focused. QFD theory is applied to education program design for satisf...

Quality Function Deployment (QFD) technique has been developed in the context of Total Quality Management, and it has been experimented in the software engineering domain. This paper illustrated how key constructs from QFD contributed to an development of a second version of a Quality Factor (QF) for a qualitative software evaluation, considering three distinctive but connected areas of interes...
