MULTI STAGE SOFTWARE PROJECT EFFORT ESTIMATION

Abstract—Software industries have done a lot of advancement in the development of software but the effort required to build a software project is still much difficult to estimate in advance. For the success of the project accurate effort estimation is always essential. In practice; many industries still using ad hoc methods for efforts estimation. Effort estimation is an activity performed in analysis phase of software development. There are several reasons of estimation failure, but unclear requirement is a measure problem of efforts estimation. All the requirements are not exactly known to the customer when he decides to go for software development, because user exactly do not know what he wants and developer do not know what he has to build, a lot of changes take place in the latter phases of development, due to this reason effort estimation failed.This paper is suggests a new approach of effort estimation. In this approach we performed efforts estimation in more than one step of software development and check the difference, if the difference is more then take some necessary to adjust the difference. Use of strong monitoring policies is necessary for the success of a software project [15]. Strong monitor policies allow us to track slippage and take some necessary action to adjust this slippage
