Abstract
Systems engineering reuse is the utilization of previously developed systems engineering products or artifacts such as
architectures, requirements, and test plans across different projects. Such reuse is intended as a means of reducing development cost, project schedule, or performance risk, by avoiding the repetition of some systems engineering activities. Although projects involving systems engineering reuse are becoming more frequent, models or tools for estimating the cost, benefit, and overall impact on a project as a result of reusing products or artifacts have not yet been adequately developed. This paper provides an overview of systems engineering reuse and recent developments with the Constructive Systems Engineering Cost Model (COSYSMO) to estimate the effect of reuse on systems engineering effort. The overview of systems engineering reuse includes a review of how reuse is handled in other domains and results from an industry survey. The recent developments in COSYSMO presents on-going research in the creation of a reuse extension for the model such as the identification of categories of systems engineering reuse, reuse extensions for the size drivers in the model, and a revised set of cost drivers.
