Design for Six Sigma (DFSS): a technical and economical analysis of its application in the Vehicle Development Process 2004-01-3308

The existent competitiveness in the automobile industry has been taking their manufacturers to an incessant search for methods and processes that seek the production of vehicles with quality and accessible costs to their costumers. The Vehicle Development Process (VDP) became an essential element for the success of a vehicle in the market, because the companies found out that, when concentrating their efforts during the development phase, the opportunities for product improvement will be much less onerous when compared with the costs spent when the vehicle are already in production. On the other hand, those improvement opportunities are evidently more difficult of be pointed during VDP than when the vehicle is already in production. This article aims to evaluate how the Design for Six Sigma (DFSS) methodology can be applied to the vehicle development process in order to provide significant results in terms of quality improvement, cost optimization and reduction of development timing.
