Integrated Engineering is a BISE-model and combines the following dimensions within an network-oriented SME: Cooperation engineering: networking of product features, process features and project parameters (internal Relationship Management); Collaborative networking: initiation, management, controlling of business relationships along the value chain (external RM); Corporate range: adaptation of the xRM-principles to the product development process (project engineering), to the complexity management (variants engineering) and to the life cycle engineering. Integrated Engineering consists of 3 modules: myPEP_cube: customized integration of product features, process features and engineering rules based on the specific product development process (PEP); myVariants_cube: customized integration of the value-added system, the variants life cycle and the variants design rules based on the complexity management system; myxRM_cube: customized integration of the corporate know-how, the collective competence and the collaborative guide lines based on the product- and technology life cycle process within the production network.
