What key performance indicator (KPI) to use when ?

摘要

I HAVE OFTEN COMPARED the use of KPI's with the fairytale "The emperor's new clothes" by Hans Christian Andersen. In short the fairy tale is about two weavers who promise an emperor a new suit of clothes that is invisible to those unfit for their positions, stupid, or incompetent. One day the emperor parades in the town before his subjects in his new clothes, a child cries out, "But he is naked!" Then all people admitted and said the same thing. Before the child said it no one wanted to admit they were stupid or incompetent.
