New Coupling and Cohesion Metrics for Evaluation of Software Component Reusability

An account of new measure of coupling and cohesion developed to assess the reusability of Java components is proposed in this paper. These measures differ from the majority of established metrics in two respects: they reflect the degree to which entities are coupled or resemble each other, and they take account of indirect couplings or similarities. An empirical comparison of the new measures with eight established metrics is described. The new measures are shown to be consistently superior at measuring component reusability.
