The quality/ability/extent of being reusable.
Reusability is a system quality attribute as it refers to the extent to which a system or its components can be utilized in other systems or applications without requiring significant modification or reconfiguration. It is also a non-functional requirement as it focuses on performance, maintainability, and scalability aspects. Furthermore, it can be considered a cross-functional constraint as it affects multiple aspects of a system, including its design, implementation, testing, and deployment. In short, reusability is an important attribute that helps reduce development costs, speeds up time-to-market, and enhances the overall quality of software systems.
Define reusable: Reusable in the context of computers and software refers to code, scripts, modules, or applications that can be used again in different contexts or projects without modification, saving time and effort. These reusable components are generally designed to be generic and adaptable to different scenarios, making them a cost-effective and efficient way to build software solutions. In general, reusable code is characterized by its modularity, maintainability, flexibility, and portability.
