But that kind of profiling involves human judgement in a qualitative way, which is not very popular in the US. Instead, we prefer to use metrics, which we can mesure, aggregate and compile in neat reports. But metrics are a projection of a multidimensional situation onto a few dimensions, and hoping we picked the correct projection. I'm all for collecting stats but I wish that was just a tool used in addition to a broader qualitative approach.
