Conception and Experience of Software Reuse and Reusability Metrics and Models - an Academic Review

There are already a number of studies and "success stories" about practical applications related to software reuse. For the most part, however the actual benefits of reuse, particularly for concrete technologies are difficult to verify. As organizations implement systematic software reuse programs to improve productivity and quality, they must be able to measure their progress and identify the most effective reuse strategies. This is done with reuse metrics and models. In this paper, metrics and models of software reuse and reusability have been reviewed and provide a classification structure that will help users select them. This paper also focuses on a description of the project's metrics-oriented terms of reference. Six types of metrics and models are reviewed: cost-benefit models, maturity assessment models, amount of reuse metrics, failure mode models, reusability assessment models and reuse library metrics.
