QFD for customer-focused requirements engineering

Abstract

Here 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 practice, are introduced. Experiences in practice with these software QFD models are presented as well. Finally, through explaining the main principles of a special QFD variant for e-commerce, called continuous QFD (CQFD), we will show that QFD is suitable for planning electronic business applications as well.
