I like the post at the bottom, http://pmarcatweetsasblogposts.tumblr.com/post/73631082205/m... , which starts with:

""" The problem with arbitrary metrics in complex situations — they tend to backfire. Give emergency services drivers rigid response time metrics, and they’ll tend to stay close in to urban centers. Surprise!

Andy Grove had the answer: For every metric, there should another “paired” metric that addresses adverse consequences of the first metric. Many companies and especially governments violate this principle continuously, and are startled by the result — every time. """

This last bit - Grove's paired metrics - does not seem nearly as widely known as it probably should be.
