“Agile” preaches: people need to focus their attention to what is most important, it refers to maneuverability, adaptability and ability to change to changing environments. This dynamism brings out many questions which are always asked “How estimation can be done in an agile way that would fairly & accurately measure size of the release?”

An estimate using the suggested Agile Estimation Model is based on the fact that the person doing this estimate has medium understanding of the problem domain, system size and architecture at the stage at which the estimate is made.
Estimation is done after breaking down the work into tasks and subtasks and estimating effort on each of these items based on “Optimistic”, “Pessimistic” & “Most Likely” effort sizing. Initial estimates & adjustments factors taken together help us arrive at an Agile Estimate, capable of estimating for a release involving complex tasks, distributed multiple teams, including developers with variable technology and domain knowledge, dissimilar work environments.
