Why do you think projects always are late? That’s because they are designed to be late. But I’ll let you in on a secret: late projects are run by wimps. Unstoppable projects are run by masters. Welcome to the philosophy of power estimation.
You see, estimation isn’t about guessing how long a project will take, it is about getting power. More budget = more power. The best way to get more budget is to leverage the fear of failure by insisting on perfect estimation.
The beauty with estimation is the more people you ask, the bigger the estimation gets. So ask lots of people. Use historical data to cross reference how much off a project can get and grow your estimation by π. Feel the power now?
