EstimationEstimation is the art of scienceEstimation is the feasibility
reportEstimation provide a road map
for success software engineering
All software product depend upon estimation

started in late 90s COCOMO'81 is not enough to apply to
newer software development practices COCOMO II has three different models The Early Design Model The Post-Architecture Model The Importance of Good Estimation
