I loved it because I enjoyed the analysis and strategy involved in getting the job done as fast as possible- which thing should we do first? next?, in getting poorly motivated workers to enjoy what they were doing, and in helping nasty supervisors turn a little nicer (psychological strategy).
Wow, that is a very positive outlook! You do have to be careful about getting the job done too quickly, though. You have to look busy while you are at work. It is even worse if they pay you an hourly wage and they send you home when you finish.
