Software reuse of a system consists of four processes: development

Software reuse of a system consists of four processes: development management support and reuse of reusable assets (building blocks).
2) Component technology A component is an interchangeable physical part of a software system that encapsulates an implementation body (which fulfils a function) and provides a set of methods for implementing the interface. In order to assemble the components developed by different software manufacturers on different hardware and software platforms into an application system the interoperability between the components of heterogeneous platforms must be addressed
