One thing about metrics, though, is that they are only marginally useful as one time measurements. Real value comes from watching metrics over time and noticing trends. Once a baseline has been established (say for code coverage), then you can set goals and work to achieve them (like ensuring coverage doesn’t precipitously drop).

Check out <a href="http://www.stelligent.com/content/pureCms.php?section=Misc&page=product-convergence">Convergence</a> and watch this (dated) <a href="http://vanwardtechnologies.com/demo/ConvergenceDemo2_viewlet_swf.html">demo </a>(features the Java edition, however, the .NET edition has the similar features).

Greetings, Great post about these tools. These tools are really good, but the practice is left unfished if there is no mechanism for side-by-side comparison between revisions. Do you know of any tools that can accomplish this? For example, we are using Subversion for source control and I cannot find any good tool that can give me so much as a simple Lines Changed / Lines Added / Lines Deleted report for two given revisions. That would be a great start, but being able to use something like NDepend or one of these other tools to line up the stats between one version of a project and another and show the measure of improvement or worse, regression, between the two would be nothing short of amazing. Side by side metrics?
