A new management process to analyse the automotive components' complaints through DMADV

Design For Six Sigma (DFSS) is a methodology able to join innovative thought to several analytic tools in order to design products, services and processes. The target of this methodology consists of reducing development time and cycle time through combined efforts of many resources and through process design within specification target and in compliance with excellence. Usually design and development are independent activities on other internal functions of the same organization, but this doesn’t occur with a right approach such as DFSS. Exactly a work group is made up of interdisciplinary experts: know-how holder, statistical method experts and prospective customer especially internal one; all this is useful to tackle the problem with an overall view. An important aspect of DFSS is to transform the reactive design approach in a more proactive approach. In particular this requires: to understand what the customer wants up front, to control the critical design parameters as part of the analysis, to calculate the design capability, to measure and to test in quality rather than to predict and design in quality. The main reason DFSS helps start with inherently more robust products or processes is the focus on impact of uncertainties as part of the design process. DFSS improves the design process by adding more discipline to the up front modelling and analysis in order to obtain a correct new products or processes introduction; it helps to do this by means of driving for transfer function between CTQs and Design Parameters.
