A Reuse Definition, Assessment, and Analysis Framework for UML†

Despite the popularity of component-based models, languages, and tools, there is an absence of reusability assessment/analyses throughout the design and development process. Software engineers must be allowed to precisely measure the potential and actual reuse of software artifacts to achieve domainspecific reuse for an organization's current and future products. Towards this goal, our previous work provides a formal framework for reusability assessment of components and classes via metrics and refactoring guidelines/algorithms, at the development stage. This paper significantly extends that work by incorporating reuse definition, assessment, and analysis into UML at the design stage, prior to the existence of code. Specifically, we expand our reuse model/framework to include dependency tracking in use case and class diagrams in support of reusability analysis and refactoring for UML. We discuss the integration of these extensions into Together Control Center, for reusability measurement across UML to support reuse from design to development.
