Incomputer programming,reusability describes the quality of asoftware asset that affects its ability to be used in asoftware system for which it wasnot specifically designed. An asset that is easy toreuse and provides utility is considered to have high reusability. A related concept,leverage involves modifying an existing asset to meet system requirements.[1]
The ability to reuse can be viewed as the ability to build larger things from smaller parts, and to identify commonality among the parts. Reusability is often a required characteristic ofplatform software. Reusability brings several aspects tosoftware development that do not need to be considered when reusability is not required.
Reusability may be impacted by variousDevOps aspects including:build,packaging,distribution,installation,configuration,deployment,maintenance andupgrade. If these aspects are not considered, software may seem to be reusable based on itsdesign, but may not be reusable in practice.
Many reuse design principles were developed at the WISR workshops.[2] Although lacking consensus candidate design features for software reuse include:
