Supporting the system architect: Model-assisted communication

System modeling and analysis is used to validate assumptions, increase understanding, synchronize views, and support decisions. By measuring indirect related quantities and commonalities of different modeling techniques in practice we can get an indication of the value of modeling. In this paper, we discuss how to increase modeling value and provide more effective model-assisted communication by understanding critical success factors of modeling. We analyze models used to support production line design at Volvo Aero Norge AS. Volvo Aero Norge AS manufactures jet engine components for commercial and military engine suppliers. Flight safety is fundamental in the domain which translates to comprehensive component quality and traceability requirements. Long-term engine programs make production line development and process improvements important for staying competitive and maintaining a profitable production that supports the required quality level. System modeling and analysis is applied to communicate insight between stakeholders and visualize different aspects of production lines and processes. In this paper we present impact factors the architect can use to increase a model's ability to assist communication. We argue how balancing and utilizing the right quantity of these factors increase modeling value. © 2010 World Scientific Publishing Company.
