It talked about some company moving oil around in barges, the setup was unprofitable and a new manager was brought up to fix it. He created metrics of the business, but didn't put any goals or goalposts for the barge crews and other managers in the company.
All he did was simply print the metrics and glue them on every barge of the fleet weekly. Soon the whole project was massively profitable. Apparently the captains of the barges would compete with each other to see who could save more money, without any penalties for the low performing nor any rewards for the high performing barges.
One thing that was very surprising is that the barges were given freedom to choose where to source materials and, more importantly, the fuel. Before the metrics the captains would pick whatever was closest no matter the prices, after the metrics the captains would, on their own, try to source fuel from the cheapest place that they could. No amount of central planning could have been as optimal as the prices fluctuated a lot from day to day, so whenever a captain saw a good deal he would re-fuel.
It turns out that empowered people want to do a good job and want to save money.
