Project managers must make time estimates at the beginning of every project because the sponsor needs to know when the project will be done. The sponsor wants to be sure the project manager will meet their due date expectation. “When are you going to be done?” is probably the the question that’s asked most often in project management.  Time estimation includes the amount of work and the amount of time (duration) required for the team members’ assignments. They are probably the most important estimates and they have to be accurate. There is a tremendous advantage if the team members participate in the time estimation process. When the team members participate in making the estimate and they think the estimate is fair, they have a commitment to finishing their work within that time. Adding all the estimates from the individual team member assignments up to the final deliverable is called “Bottom up”  time estimation. The accuracy of the time estimates is a major determinant of a project manager’s credibility with upper management, stakeholders and the project team.

The video shows a technique for time estimation that 60% of project managers use. But it is the wrong way. It creates time estimates that no one believes so no one is committed to them. After you watch the project manager work with the team, you’ll go behind-the-scenes and hear what the team members say about their time estimation session. You’ll also hear from the project sponsor about the completion date he set. Then I will give you my assessment of what happened, the impact on the team members, the level of commitment they have to their dates and how the project manager should have done things. I hope you enjoy it.
