Analyzing the Factors Affecting Reusability for Black–Box Component

Component-Based Software (CBS) has emerged as more generalized approach for application development. In Component-Based Software Engineering (CBSE), it is required to measure the reusability of components in order to improve the reuse of components effectively because reusability is an effective way to increment the productivity in CBSD; it is required to calculate the reusability of components. However, due to the component’s black-box nature the source code of the components are not available for the users, so it is difficult to use conventional metrics of Object-Oriented metrics in Component-Based Development (CBD) as these metrics require source codes of the components. Now here this study examines various factors to measuring software reusability. Knowing that what makes software “reusable” can help us learn how to build new reusable components and help us to identify potentially useful modules in existing programs and proposing three factors model that affects the reusability of the component directly.
