Agile Development
1. Story points
2. Velocity = user story points completed per iteration
3. Burn out = number of sick days per iteration due to unreasonable estimates
4. New hires = number of new developers you have to hire because the old ones quit
At Pivotal, developers always gave the estimates (fib: 1,2,3,5,8 was most commonly used). If the story was > 3 points, it was broken into smaller stories. Thus, you were never working on stories that were more than 0-3 points and by then, most of the stories were pretty clearly defined, easily estimated units of work.
