Abstract
The present article intends to describe a new and viable problem solving approach, as an alternative to 8D(isciplines) methodology, ideally to be implemented especially during the product development processes. The proposed methodology is based on the Robust Engineering principle (Taguchi Method with his P Diagram, the design of experiments as fractionated arrays and the S/N ratios), fact that brings an important degree of efficiency to the implementation process, as a mandatory requirement of the ISO/TS 16949:2009, for the certified organizations which are involved in a continuous improvement process. Taking in consideration the implementation risks is a very important aspect, too, because the methodology need to be as efficient as it is possible even if it is implemented by internal specialized employees or by external consultants. So, for this last case, the main risk may be the organization’s resistance against an external specialist. The final validation of the optimization parameters (at their optimal levels) proposed by implementing the problem solving methodology is mandatory and it must be realized in the same test’s environment. The proposed methodology may be implemented, practically, for all kinds of products that are developed within the machine building sector, but this article is focused on the automotive sector implementation.
