Isn’t it interesting that in the second decade of the 21st century after yet another CHAOS Report tells us that only 21% of reviewed projects deliver the agreed scope on time and in budget that many of us still cling to the illusion that accurate estimation is merely a question of training, practice and discipline? What amazes me is that I know a handful of people who can consistently correctly guess how long a project will take.
Most of us mortals regard projects as an adventure into the unknown. At the beginning of the journey you have scant information about what you have to deliver and then your sponsor has the nerve to ask you exactly how long it’ll take or imposes an unrealistic deadline.
