What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

There is no engineering of successful systems without any changes; they are the rule and not the exception in product development. To uncover the problems, rationales and goals associated with changes during the life cycle of a system, an exploratory case study in German industry was conducted. Causes and reasons for changes are described, as well...
For the reengineering of development processes and for its
continuous improvement, the development process has to be modeled and
documented. A process map is the basis for the way how a system will be
or has been designed. The standard methods and tools for process
modeling are mostly used for business process modeling and redesign. Due
to the spec...
There is no innovation process and no engineering of successful systems without any change, but it is absolutely necessary to understand and have a good grip on changes. Based on an analysis in German industry, five strategies are proposed to overcome problems and risks of changes in product development.

... Thus potential changes become transparent throughout the system and design changes within one subsystems can be assessed from a system point of view. This leads to reduced time and cost effort on synchronising the different subsystem designs, as especially the five Change Management Strategies (Fricke et al., 1997 If the customer changes his requirements, immediately their impact on the design can be assessed and discussed with the customer. This helps to find cost-efficient solutions for the customer by explaining the impact of different requirements. ...
... In this framework, flexibility and adaptability are distinguished by either an external or internal agent, respectively, regarding their location to the system boundary, initiating the change in the system [6]. For example, [18] related the flexibility of a fleet of aircraft to their reliability and availability. Instigating a change affects the design parameters comprising a system in some quantifiable way. ...
... As already mentioned in chapter 2.3, the different users pursue different goals. A variety of modelling goals can be found in literature (see Bichlmaier, 2000;Browning, 2010;Fricke et al., 1998;Kreimeyer, 2010). Starting from these, the following modelling purposes for optimisation of data and information flows and support designers in their daily work were identified: ...
