Why is estimation difficult in software engineering? Time estimation in software engineering is so difficult because estimates have so many flaws in the first place. For starters, once an estimate and target delivery date are given, they are usually set in stone. They are treated as commitments when they should not be considered as commitments in the first place.
Why is software estimation so hard? Because software engineering projects typically have a higher level of uncertainty and its very difficult to accurately estimate the time required to do work when there is a high level of uncertainty associated with the work to be done.
What are the difficulties of project estimation? The challenge with Project estimation in software development, unlike other industries, is that it’s often done with partial data and sometimes with incorrect data, too.
