Development strategies in design and process planning quality assurance context

According to the new development strategies, the product development focuses on as much as possible parallel execution of all development related product life cycle phases, thus creating CE (Concurrent Engineering) approach. Its further extension is CEE (Cross Enterprises Engineering) approach incorporating the relations between business and engineering activities, so securing also the access to the resources of cooperating enterprises. Computer integration of product phases can be viewed as functional, informational and complex integration. The process planning quality is assured on the design and technological process planning stage with the use of methods and systems processing the data from the other product development phases. The paper presents the methods and systems for design and process planning quality assurance in the product life cycle as well as the possibility for the implementation of the presented product development phases.
