    Open source innovation is a well-studied phenomenon of the ICT sector, but its evolution towards the field of tangible hardware product development is a newer phenomenon which remains mostly theoretical. Existing literature has identified that to push existing open source product development (OSPD) practice towards the achievement of high quality complex products, methods and tools adapted to this specific organisation of work are needed. The objective of this article is to explore the practices emerging from OSPD communities in order to support the development of appropriate process support in the future. It reports first observations made during a qualitative and comparative empirical study performed with participants of 23 OSPD projects through semi-directed interviews. Activating a formerly published framework, these observations address four themes: the organizational structure of OSPD's surrounding communities, their design process, their underlying business models and the supporting online tools they use. The preliminary results are delivered to the engineering design and management scientific community as an impulse for further research.

    The multi-perspective modeling method is an enhancement of enterprise modeling and will enable understandable, operational views ("perspectives") on sustainable value creation. The goal is to allow all stakeholders to make decisions towards the sustainability in their context, ranging from individual enterprise decisions up to cooperation strategies. As known, the sustainability is based on the environmental, economic and social dimensions. The energy and resource efficiency is an essential subset within the sustainability context that affects mainly the first two dimensions. This paper presents an enterprise modeling driven and supported analysis of energy and resource efficiency, which was performed at several small and medium sized enterprises. The experiences gained from this application case are described and their consequences for the multi-perspective modeling method are argued.

    Die heutige Produktentwicklung ist durch kollaborative Prozesse zwischen vielen verschiedenen Partnern und eine intensive Nutzung von digitalen Werkzeugen und Produktdaten gekennzeichnet. Die effiziente und effektive Zusammenarbeit wird dadurch zunehmend zum Wettbewerbsfaktor und hat einen starken Einfluss auf die Prozess- und Produktqualität in der Entwicklung komplexer Systeme. Um die Qualität dieser Kollaborationen in der Produktentwicklung messbar und bewertbar zu machen, soll am Fraunhofer-Institut für Produktionsanlagen und Konstruktionstechnik (IPK) sowie an der Technischen Universität Berlin ein Reifegradmodell zur Kollaborationsfähigkeit entwickelt werden. Zum Aufbau dieses Modells sowie zur Gewinnung von konkreten Zahlen zur Ausprägung von verschiedenen Aktivitäten in der heutigen Ingenieursarbeit dient eine groß angelegte Studie, welche vom Geschäftsfeld Virtuelle Produktentstehung am Fraunhofer IPK , der Contact Software GmbH sowie dem VDI durchgeführt wurde. In ihr wurde von einer neutralen und gleichermaßen wissenschaftlichen Perspektive aus die Ingenieurarbeit in kollaborativen Entwicklungsprozessen untersucht. Im Wesentlichen bestätigte sich die Hypothese, dass den Ingenieuren zu wenig Zeit für die eigentlichen Kernaufgaben wie das Entwickeln, Konstruieren und Absichern zur Verfügung steht. Gründe liegen hierfür vor allem bei organisatorischen Aspekten. Diese Erkenntnisse werden beschrieben. Sie ermöglichen es, die richtigen Ansätze für ein Reifegradmodell zur Kollaborationsfähigkeit zu definieren.

    Multi-perspective modelling of sustainability aspects within the industrial environment and their implication on the simulation technique

    Modelling is a broadly accepted analytic instrument and planning tool. Today, modelling is mainly applied for engineering and physics purposes and covers a short time horizon when compared to intergenerational justice. In parallel, sustainability is gaining increased importance for the industrial planning, because themes like global warming, child labour, and compliance with social and environmental standards have to be taken into account. Sustainability is characterized by comprehensively examining the three dimensions of economic, environmental, and social questions as well as their long-term perspective. Adequate indicators and an adaptation of modelling and simulation methods and procedures are necessary to evaluate the sustainability of industrial processes. A further challenge is the consideration of sustainability effects coming from the usual manufacturing process structure of a value creation network, in particular from cross-company cooperation and geographically distributed production. This article analyses the implications of those advanced tasks on the simulation technique and its application and proposes a conceptual framework for the modelling and simulation of such networks, which differentiates the effects of sustainability by the level of decision-making within enterprises.
