Any metric or KPI can be gamed.

Comic from Lokad's supply chain series, titled Any metric or KPI can be gamed, depicting a medieval french dictionary writer at work and his student staying behind him. The writer is sitting in front of a big handwritten book and writes new words with a feather 'restock - réapprovisionnement'. The scene is separated in two so we can see what he is writing. He says to his student 'They pay me by the letter'.
