    In this paper a methodology for improving mechatronic development processes is presented. The methodology has been developed in the German joint research project MIKADO funded by the German Federal Ministry of Education and Research (BMBF). It describes a comprehensive procedure for process improvement based on a set of reference process models and supported by specific software applications. In a first step the procedure specifies how to generate process models based on an existing process or for planning a new one. In the following analysis phase optimisation potentials in the generated process models are identified. This phase is supported by a set of predefined reference process models that indicate - from a mechatronic view point - at which time during the development and how multidisciplinary coordination activities have to be carried out. A comparison of the generated process models with these reference process models and the application of questionnaires reveals the optimisation potentials that are subsequently used as a basis for improving the generated process model. The improved process model is then used for process control in a workflow management system (WfMS). The methodology has been evaluated against industrial requirements by two medium sized enterprises in the micro-production domain and in the solar energy systems domain. In Section 14.2 the problem statement will be presented. In Section 14.3 the current state of the art in model-based process improvement approaches is presented and the need for the development of new approaches is motivated. Section 14.4 describes the improvement process, the reference process models and the results of the evaluation. Finally Section 14.5 presents the conclusion drawn from the evaluation and future research topics.

    Die Entwicklung innovativer und zugleich wirtschaftlicher Produkte sichert einem Unternehmen langfristige Wettbewerbsfähigkeit. Um wachsenden Anforderungen an Qualität, Zeit- und Kosteneffizienz in der Entwicklung gerecht zu werden, unterstützen informationstechnische Systeme den Entwicklungsprozess. Die Systemlandschaft entlang des gesamten Produktentstehungsprozesses wurde im Rahmen zweier Studien untersucht. Eine Studie befasst sich mit dem Einsatz von CAx-Systemen in kleinen und mittleren Unternehmen, um Potenziale für die Nutzung und Weiterentwicklung der Systeme zu identifizieren. Die zweite Studie verfolgt das Ziel, Erkenntnisse über den Systemeinsatz in großen Unternehmen zu erlangen, um analysieren zu können, ob Unternehmen ihre Produktentstehungsprozesse an verfügbare Systeme anpassen oder die Systemauswahl anhand vorhandener Prozesse erfolgt.

    Product creation is facing the next level of fundamental changes. Global demands are growing substantially to achieve energy efficient and sustainable value creation networks for products, production and services without compromising traditional success factors such as time to market, cost and quality. To stay competitive within such an environment development partners in industry and public sectors will require new interplay solutions for engineering design execution, domain knowledge representation, expert competence utilization and digital assistance systems. This scenario offers the chance for virtual production creation solutions to become critical for the future by offering unique engineering capabilities which have not yet explored or deployed. The paper investigates key elements of modern virtual product creation such as agile process execution, functional product modeling and context appropriate information management towards their competitive role in satisfying increasing numbers of product requirements, in delivering robust systems integration and in ensuring true sustainable product lifecycle solutions.
