Considerations for a Generalized Reuse Framework for System Development
Gan Wang, Jeff Rice · INCOSE International Symposium · 2011
Abstract Reuse has been gaining ever increasing focus in all stages of the system development process as the prospects of leveraging prior investments to save costs, shorten delivery schedule, and possibly improve product quality are appealing to system developers. However, the concept of reuse at the system level is often poorly understood and the practice has not been effectively documented and practiced, particularly from the systems engineering point of view. This paper conceptualizes a generalized reuse framework for system development using an activity‐based modelling approach. It examines reuse from both the producer's and consumer's points of view and links the essential reuse activities for the production and consumption processes through reusable resources. A classification schema is proposed to evaluate reuse from the two perspectives, i.e., development with reuse and development for reuse. The interface between the two strategies is discussed and notional scenarios to apply this framework are also presented. The framework proposed lays down a foundation for quantitative evaluation of the effect of reuse in an on‐going effort assessing such an impact through parametric modelling.
