I agree that 1.1.C's interface was a bit baroque. I think the product is well worth the money, since it is an integrated tool providing measurement, assessment, and expert rule based estimation, based on methodologies that have taken years to develop. Checkpoint forces managers to think about these issues and helps them make reasonable decisions. It provides a framework for measurement and tracking improvements in productivity and quality. I have used a crude form of function point analysis as an estimating tool, with quite a bit of success.
Prices are reasonable.
Both run on PCs or Suns, among others. There is an interesting but preliminary correlation between the code coverage of a test suite and defect removal efficiency, or the percentage of latent defects actually detected. It appears that defect removal efficiency approximates the 0.75 power of coverage. Another interesting new correlation is that Function Points provide a direct metric for predicting test case volumes during requirements and design. Civilian projects tend to average about 2 test cases per Function Point, while military software projects tend to average about 3 test cases per Function Point.
