Object-oriented software design utilizing Quality Function Deployment

This paper puts forward Quality Function Deployment (QFD) technique as an effective tool for requirements acquisition and design analysis of a ground software intensive project. The paper shows how QFD focused our effort to produce a product for customers with diverse needs and also how to tailor the technique for use with modern Object-Oriented Design (OOD) software technology. The results show that the QFD process enabled us to capture requirements and produce specifications and designs that are efficient, robust, and consistent. Requirements captured with QFD were faster compared with other classical methods by a factor of 50%; more robust by a factor of 60% with respect to identification of conflicting requirements or protential bottlenecks; and more consistent by a factor of 70%.
