C. Sessions) Organization: SCI Technology, Inc., Huntsville, Al. Lines: 32 There has been some discussion in this thread of the inappropriate use of metrics to evaluate individual contributors. There seems to be a misconception that the primary risk lies in using metric-program data to evaluate individuals; would that this were so. There is, unfortunately, a serious risk in the process itself, as used to improve S/W development procedures, as illustrated: At a large and *very* well-regarded institution, the metrics program had determined that successful projects devoted A % of applied time to initial specification, B % to initial design, C % to coding, D % to debugging, etc. Having determined this, individuals were expected to conform to the profile. One misfit, for whatever reason, spent more time on the initial phases and (perhaps as a result) converged more rapidly on working product. (Maybe the relatively short test programs had something to do with the fact that his products used DFT principles, or perhaps with the fact that he spent more time on the test plan -- who knows?) As with any nonconformist, his misguided notions eventually resulted in his downfall. When evaluation time came around, he was upbraided for insufficient attention to debug & test. The word got around, and other developers who had been thinking of trying to match his consistent on-time low bugcounts rapidly disabused themselves of the notion.
