INTRODUCTION
In this chapter, we will cover the history of quality function deployment (QFD),
describe the methodology of applying QFD within the software Design for Six Sigma
(DFSS) project road map (Chapter 11), and apply QFD to our software example.
Within the context of DFSS, El-Haik and Roy (2005) and El-Haik and Mekki detailed
the application of QFD for industrial products. The application of QFD to software
design requires more than a copy and paste of an industrial model. Several key lessons
have been learned through experience about the potentials and pitfalls of applying
QFD to software development.
QFD in software applications focuses on improving the quality of the software
development process by implementing quality improvement techniques during the
Identify DFSS phase. These quality improvement techniques lead to increased pro-
ductivity, fewer design changes, a reduction in the number of errors passed from
one phase to the next, and quality software products that satisfy customer require-
ments. These new quality software systems require less maintenance and allow in-
formation system (IS) departments to shift budgeted dollars from maintenance to
new project development, leading to a (long-term) reduction in the software de-
velopment backlog. Organizations that have published material concerning the use
of QFD application to software development include Hewlett-Packard (Palo Alto,
CA) Rapid application development tool and project rapid integration & manage-
ment application (PRIMA), a data integration network system (Betts, 1989; Shaikh,
