In order to achieve quality goals; adequate methods have to be used during all phases of the product life cycle. In particular preventive quality engineering methods play a decisive role for product quality and product costs; which are widely determined in the early stages of the product development process (cf. VDI 1994; p.5). To enhance the quality capability of the product development process; various process models and guidelines have been developed (cf. Moehringer; 2005). They rely on a large multitude of methods and techniques and are all aiming at one common goal: preventing faults - preferably in the early stages of the development process.
Despite all these efforts the number of breakdowns and factory recalls does not seem to diminish (cf. KBA; 2006). Obviously risk potential remains; which is not or only partially addressed by the conventional; mostly isolated; application of these methods. By integrating different methods; advantages of several complementary approaches are combined in order to identify faults and their potential causes more effectively (cf. DIN; 2005; p.11). Work in this field has already been done combining methods such as QFD and FMEA (Sesma Vitrian; 2004) or FMEA and FTA (DIN; 2004; p.8). Thus the contribution to the quality capability of a product is more than the sum of the outputs of separately used techniques. To show the potential of this method integration a conjoint use of Fault Tree Analysis (FTA) and the DeCoDe method of Demand Compliant Design will be discussed.
