Maintainability Metrics of UML Design
Iryna Zaretska, Maryna Besedina · 2012
The paper introduces a new object-oriented metric to evaluate maintainability of the software system at the design stage. Unlike well known object-oriented metrics applicable only to one class or to a category of several interconnected classes the proposed one evaluates the degree of extensibility for the whole static design. The metric is based on the main principles of object- oriented design and can be used by designers for evaluation and refining purposes. The results of the experiment on real projects to check this metric are reported. The Java plug-in for calculating this metric in UML Case tools is presented.
