Estimate gives an idea of time required for the completion of the work. COCOMO Conclusions The cost estimate is the financial spend that is done on the efforts to develop and test software in Software Engineering. Hence, these models are based on common sense. An Estimation & Rate Analysis Software Construction cost estimator is designed to automate and speed up the process of Estimation, Analysis, Tendering and different related tasks. Estimate is required to invite the tenders and Quotations and to arange contract.
