Checkland argued is misleading and should be avoided We do not fully share Checkland’s scepticism about as-ifobjective descriptions of social structures and processes But it is important to recognise that a very high degree of consensus about a skeleton of social facts does not imply a shared perception of their implications, and that alternative views of how processes work may be equally legitimate and. .. different expectations of them Rather than prescribing an interpretation of models, the understanding of the role that models can play in an organisation needs to be negotiated within a team and an organisation An understanding of a model is a cognitive construct rather than an inherent property of the model, and a shared understanding is constructed through social processes of discussion and clarification... important that designers and managers models can play in an organisation needs to be negotiated within a team and an organisation An understanding of a model is a cognitive construct rather than an inherent property of the model, and a shared understanding is constructed through social processes of discussion and clarification understand that models can be interpreted in different ways and that people have... Every product engineering process is unique and individual This is the first out of five hypotheses about product engineering processes (Albers, 2010) In this paper we investigate where the differences between product engineering processes originate from We examine the integrated product engineering model (iPeM) and its subsystems - the triple systems: system of objectives, system of objects and operation... (see Section 2.3) - and point out reasons for distinctions between individual processes Not only processes themselves are individual but also their sub -processes with their networked hierarchies of activities, hierarchic levels of systems of objectives etc In Section 2.2 we review the iPeM as a model of engineering processes, its different abstraction levels and the related state of the art The sections . class="bi x0 y0 w0 h1" alt="" Modelling and Management of Engineering Processes Modelling and Management of Engineering Processes 123 Peter Heisig · P.
