As I said, we suck at predicting future.
It's not just estimations. Estimating is really a small part of it. We make incorrect assumptions about the requirements. Project scope changes. Someone had to take a sick leave...
The further we are in a project, the more we know about it and only then we can tell whether we'll be on time. Sometimes we have to re-estimate or reevaluate.
and estimates is what it is: an estimate. An estimate is a guess. No commitment is implied. No promise is made. Missing an estimate is not in any way dishonorable. The reason we make estimates is that we don’t know how long something will take.
The problem here is that business and management often view estimates as commitments.
