A NAF-based proposition to leverage system engineering change management in systems-of-systems acquisition project teams

Abstract

A key issue in systems-of-systems acquisition agencies is enforcing effective use of System Engineering at the scale of project teams. Usual change management strategies would not bypass the high cost of architecture modelling at the scale of a system. This article proposes a pragmatic approach to minimize this investment by gradually incorporating engineering works from specific domains, in order to constitute a NAF-based technical-oriented referential. Use cases and a case study highlight how such a referential can be exploited to fuel technical analyses, then the decision-making process of the acquisition project, and thus providing incentive to the team to get leverage for System Engineering change management.
