At a previous company, where the IT team reported to me, most big IT projects ran behind schedule and went over budget. And this seems to be a common experience for business executives. Yes, technology can be complicated. However, that does not explain why IT projects typically go over budget and run behind schedule.
A few years ago, I decided to figure it out. It was important to the success of Skyriver IT. The answer surprised me but also made a lot of sense.
Most IT people are task oriented, and have not been trained in good project management. If you ask most engineers how long it takes to set up a new server, they will tell you about four hours, and they are right. However, that only includes the time it takes to do the actual setup once everything is ready.
