Software Reusability Evaluation in Component Libraries

Abstract

Software reusability evaluation is important in component libraries because reusable components can reduce development effort, improve consistency, and support faster software delivery across multiple projects. Component libraries often contain classes, services, modules, APIs, utilities, templates, and interface definitions that must be understandable, adaptable, reliable, and easy to integrate. Traditional reuse decisions may depend on developer experience or informal selection, but this can lead to poor component choice, duplicated implementation, integration difficulty, and maintenance problems. This article focuses on software reusability evaluation in component libraries by examining modularity, interface clarity, documentation quality, dependency level, configurability, test coverage, usage frequency, and defect history. The study discusses how structured reusability metrics can help identify high-value components, remove weak or obsolete assets, and improve library governance. The article concludes that systematic reusability evaluation can strengthen software reuse, reduce development cost, improve maintainability, and support long-term quality in component-based software engineering.
