If the criterion changed to safety, you would get more 11 drivers who obeyed traftic laws. But both these criteria would be at the expense of time. There is another 12 : people became immensely inventive in hitting targets. Have you 13 that you can leave on a flight an hour late but still arrive on time? Tailwinds? Of course not! Airlines have simply changed the time a 14 is meant to take. A one-hour flight is now ballad as a two-hour flight. The 15 of the story is simple. Most jobs are ultidimensional, with multiple criteria. Choose one criterion and you may well 16 others.Everything Can be done faster and made cheaper,but there is a 17 . Setting targets can and does have unforeseen negative consequences. This is not an argument against target-setting. But it is an argument for exploring consequences first.
