A Metrics Set for Reusability Based Quality Framework for Software Components

Reusability is the most important factor which cannot be ignored when practicing component based software development since it offers many advantages like improved productivity, cycle time and quality. Reusability and quality are proportional to each other as a high quality component is definitely reusable and vice versa. The quality is a subjective issue which is difficult to measure objectively. In this paper, we proposed a metrics set to evaluate the quality or reusability of black box software components. The scales of metrics are so chosen that are capable of easily grasping the behavior of components in order to measure the quality worth. The results are found highly significant when validated with Pearson correlation method.
