PROCESS MODEL FOR REUSABILITY IN CONTEXT-SPECIFIC REUSABLE SOFTWARE COMPONENTS

Constructing component based software using reusable components is becoming a promising approach. Context-specific reuse is a broadly used way to increase the value of reuse. This paper reports our on-going work aimed at reusing context-specific reusable software components from an existing system to achieve large scale reuse. Since the quality of a context specific reuse system is highly dependent on the quality of the component, quality analysis becomes very critical to the reuser. The proposed process model adopts the quality hierarchy process method to determine the reusability factor and makes the quality assessment of the reusable component more effectively for better reusability. We discuss a dynamic approach to analyze the component for reusability. The basic premise assumed by this model is that reusable components have certain quality factors like functional coverage report, time, functional usefulness etc., and which can be measured to certain extent with help of metrics. This process model combines three quality factors into reusability metrics based on the quality hierarchy process. Here, we also introduce a new algorithm for the process of reusing the contextspecific components from the existing system
