A discriminant metric for module cohesion
Thomas J. Emerson · International Conference on Software Engineering · 1984
The decomposition of a large program into modules can be guided by the use of a property called cohesion, first described by Constantine. Cohesion is a quality that describes the degree to which the different actions performed by a module contribute to a unified function. However, this technique may be difficult to apply due to the subjective nature of the definitions of levels of cohesion. In this paper a software metric is defined and proposed as a discriminant for classifying modules according to their cohesion. Formal properties of the metric are derived which can be used to set the metric value ranges for module classification.
