The purpose of the research discussed here is to establish a metric for the measurement of reuse in a generic enterprise-level model context and to use this approach to create a specific metric for a company. The paper demonstrates how a software development firm can monitor the reuse success in the development process using the measure. Traditionally, the reuse rate is defined as the percentage of the development effort retrieved as code segments from a software repository. The metric proposed here extends this definition to include reuse of generic enterprise-level model components. An example is given of the successful assessment of a reuse percentage for a software developer’s actual project.
