Once upon a weekday meeting, I had a story to tell. It was the tale of a project manager, who’s name really rings a bell. He quantified the total project cost, he didn’t miss a dime. He also computed the schedule, he was always aware of the time.
He used all these input values, with random amounts being his friend. He ran these simulations. I thought they would never end.
The outcome was a distribution, a bell curve if you like. On the edges we saw some low points, in the middle there was a spike.
Monte Carlo was this fellow’s name, he was a heck of a numbers guy. We asked him if he ever made things up. He said he would merely quantify.
Now don’t think Monte worked alone, he had a counterpart. Her name was Jane Stake-Holder, he worked with her from the start.
Jane could be quite demanding, sometimes ignoring project scope. But Monte managed the situation well, knowing creep was a slippery slope.
His technique was well documented, a change would make everything slip. He told this to Jane Stake-Holder who you'd think would do a back-flip.
But numbers don't lie and neither did he, Jane knew Monte would put up a fight. She backed down and submitted a change request, the schedule would extend to the right.
