Metrics Used

Metrics from 4 different levels including method level, class level, package level, and project level help identify where large code changes occurred as well as where exceptional or if exceptional locations exist.  Finding exceptional locations by comparing to results to average values allowed easy access to metrics results without having need a great deal of understanding of tools used to gather metrics.  Any group member can quickly look code and compare results to averages and decide where unit testing, refactoring, and code review is necessary.  Note that there is some intentional overlap since RMS and JMT seem to count differently.  RMS and JMT contain many other metrics that may be useful in the future.  Therefore the metrics data is stored within CVS for future use.
