Product Change Propagation in Early Phases of Process Development

The product change is a natural component of the development process and arises in the framework of a continuous improvement and refinement of planning inevitably. Ideally a constant information gain in the process of planning leads to a revision and an alteration of existing acceptance and concepts. A special case of the change is described by the Product Change Propagation. A local products change reproduces itself global and leads to a number of subsequent product changes, which can be measured heavily. In the complex planning surrounding the effect of a product change can be mostly not promptly recognised and will have complex correction loops as a consequence. This paper offers, aligned to the process organisation, a system-oriented approach for the early identification of planning inconsistencies by subsequent product changes.
