00:00According to the theory of constraints, you've already killed the project simply by the way you have started managing it.
00:04You've been trying to impose certainty on uncertainty.
00:06You should not have asked somebody how long it would take with a commitment to do something with an uncertain
00:12duration.
00:13The theory of constraints says, after we've trained and explained to people why we're going to do this,
00:17we ask them for two numbers for each task, the pessimistic duration and the optimistic duration.
00:22The optimistic duration is, imagine you only have that to do, you have a full kit of information,
00:27you don't have any significant problems, you don't have to do any multitasking or go to stupid meetings.
00:31If you only have that to do, what is the average time, average time that you think it could take?
00:36This is not a commitment in any kind.
00:38And to prove it's not a commitment, I mean, I'll ask you, what's your pessimistic estimate for that same task,
00:43right?
00:43If things go bad, how bad could it get?
00:45So you get two numbers out of everybody rather than one.
