I adverse using metrics for value people, while I do not adverse metrics per se, as a companion information for statistical purposes. The issue with metrics used for something it that they became a target, not a measure anymore. They push toward conformism, witch happen to be antithetic to innovation.

Using metrics to understand at a large scale what happen, if a method work or not, where to improve etc might be useful and harmless. Using them as a way to prize or penalize have regularly very bad results.

The ancient quis custodiet ipsos custodes it's equally valid for metrics, who evaluate those who design the measure?
