Is the measure of an architect the number of lines in a blueprint? Is the measure of a craftsman the number of finished goods produced? It seems to me that different projects in the same domain should use different attributes to evaluate success. Why do we attempt to use uniform measures across-the-board? Is it lazy management or does delving deep into project-specific metrics make it hard for large enterprises to compare employees in similar functions? Or something else?
