Quality Tree of QFD: A New Method to Ensure Software Quality

Abstract

We bring a new method--QTQ (Quality Tree of QFD) to solve the problem, that software quality can not effectively ensure. QTQ is based on UML profile¿it integrates ideal solution and QFD. Its main point is: According to the concept of ideal solution, establish DTRQ (Distribution Tree of Requirement Quality), when analyze requirements of customer. Use DTRQ to guide design. On the basis of design, build DTDQ (Distribution Tree of Design Quality) and assess if CRDP (Change Rates of Design Plan) is acceptable, and then coding according to qualified DTDQ. In testing procedure, software quality is evaluated by the qualified DTDQ.
