Object Oriented Metrics for Java
Develops an automated tool to collect quality-oriented metrics for Java. Defines each proposed metric and explains the potential in estimating quality. Collects sample data to check the validity of the metric collection process and compares with other data from other object-oriented languages.
Object-Oriented Metrics in Practice

Metrics are paramount in every engineering discipline. Software engineering, however, is not considered a classical engineering activity for several reasons. In general, if a software system is seen to deliver the required functionality, only few people if any care about the internals. Moreover, defining, understanding and applying software metrics often looks like an overly complex activity, recommended only to 'trained professionals'. Lanza and Marinescu demystify the design metrics used to assess the size, quality and complexity of object-oriented software systems. Based on statistical information from many industrial projects and generally accepted semantics they deduce many single and combined threshold values. They show in detail how to identify collaboration and classification disharmony patterns in code, how to visualize their results using the freely available CodeCrawler visualization tool, and how to devise possible remedies. The combination of theoretically sound results and practically tested procedures and solution paths makes this book an ideal companion for professional software architects, developers and quality engineers. The pattern-oriented description of disharmonies offers easy access to detecting shortcomings and applying solution strategies. "This well-written book is an important piece of work that takes the seemingly forgotten art of object-oriented metrics to the next level in terms of relevance and usefulness." Richard C. Gronback, Chief Scientist, Borland Software Corporation.
Validating Object-oriented Design Metrics on a Commercial Java Application
If faulty classes can be detected early in a software development project's life cycle, mitigating actions can be taken, such as focussed inspections. Prediction models using design metrics can be used to identify faulty classes early on. This paper presents a cognitive theory of object-oriented metrics and an empirical study to formally test this theory while validating the metrics and to build a post-release fault-proneness prediction model. The cognitive mechanisms applied in this study to object-oriented metrics are based on contemporary models of human memory. The empirical study was performed with data from a commercial Java application. Metrics investigated include Depth of Inheritance Tree, Import Coupling, Export Coupling, and Number of Children. Finally, the paper formulates a cost savings model and applies it to the predictive model to demonstrate whether a reduction in post-release costs occurs if the prediction model is used to identify the classes that should be inspected.
