Good quality is born from a good system. This is why a quality system is valued in the ISO.

called the quality function job functions that create quality. In QFD we call these quality
functions. A good system is where quality functions are clearly identified. The network of this
procedure is called narrowly defined quality function deployment. By combining QFD with these
standards, we are better able to prioritize the job functions for better implementation of the
improvement plans (Akao, 1999; Akao and Hayazaki, 1999; Akao and Mazur, 1998).
Six Sigma and design for Six Sigma (DFSS) are growing in use around the world. To the tools and
methods of TQM has been added financial accountability for better cost/benefit analyses of
measurement and quality control. Stronger, also, is the systemization of the quality processes and
tools into a more logical flow that is easier to teach, test, and certify. QFD will play a vital role in
improving the understanding of the voice of the customer, capturing customer priorities, and
translating them into Six Sigma directives (Mazur, 2002).

Ermer and Kniper (1998) reported benchmarking as a total quality process that is used to search for
industry best practices which led to superior performance. It is a productivity improvement tool that
helps companies to achieve and maintain competitive advantages by striving for world-class
performance. By obtaining the information needed to support continuous improvement and gain
competitive advantage, benchmarking can help QFD users make strategic decisions both from the
marketing and technical viewpoints, i.e. customer satisfaction benchmarking.
Chan and Wu (2002) reviewed QFD literature and stated that QFD is originally developed for
customer needs analysis in a product development context, the method has been adapted and gainfully
applied in many fields like quality management, product design, product planning, decision making,
management, teamwork, timing, and costing. Essentially, there is no definite boundary for QFD's
potential fields of applications. QFD combines various design, engineering, and managerial tools to
create a customer-driven approach to develop new products. QFD's early applications focused on such
industries as automobiles, electronics, and software's. The fast development of QFD has resulted in its
applications to many manufacturing industries. Eventually, QFD has also been introduced to the
service sector such as government, banking and accounting, health care, education, and researc
