Software reusability
Software reusability is a software engineering concept that describes when a previously designed and developed software element can be used in a new application with little or no rework or additional investment. A software element is one of the basic building blocks in the design of a computer software program, typically called a module, component, etc. Software reusability more specifically refers to design features of a software element (or collection of software elements) that enhance its suitability for reuse. Candidate design features for software reuse include:- Adaptable\n* Brief: small size\n* Flexible \n* Parameterization\n* Generic\n* fast\n* Simple: low complexity\n* Localization of volatile (changeable) design assumptions (Parnas)
