Quality Metrics for Object-Oriented Design Assessment

摘要

This paper presents an approach to evaluate internal attributes of object-oriented design by means of verifying and detecting design defects that are pre-defined for each of the internal attributes. We create a list of design defects that may occur when defining the structure of object-oriented design, and propose metrics for automatically detecting each of these defects. Moreover, thresholds to judge whether a metrics value indicates a critical situation, or not are defined for each of the metrics. We have made the support tool which measures metrics values from the class diagram and the sequence diagram of the UML design and detects the design defects.
