Goodhart's Law
Goodhart's law states that when a measure becomes a target, it ceases to be a good measure. In other words, if you pick a measure to assess performance, people find a way to game it.
To illustrate, I like the (probably apocryphal) story of a nail factory that sets "Number of nails produced" as their measure of productivity and the workers figure out they can make tons of tiny nails to hit the target easily. Yet, when the frustrated managers switch the assessment to "weight of nails made", the workers again outfox them by making a few giant heavy nails.
And there's the story of trying to measure fitness by steps from a pedometer only to find the pedometer gets attached to the dog.
Some strategies for helping this are to try and find better, harder-to-game measures, assess with multiple measures, or allow a little discretion.
