A reuse metrics and return on investment model

Abstract

It is argued that establishing a realistic return on investment on a reuse program is essential to inserting reuse into a corporate software development process, and that clearly stating the potential benefits of reuse in financial terms has proven to be a powerful motivator. A reuse metrics and return on investment (ROI) model that distinguish the savings and benefits from those already gained through accepted software engineering techniques are defined. Three reuse metrics are derived from readily available and observable software data elements. The metrics are used in the return on investment model to establish sound business justification for reuse. >
