Estimated SW Costing by using FPA in Early Phase of SW Development.

Costing of software is a critical activity that is performed by project manager or in some case by Business analyst. Projects are overrun due to erroneous estimation and budget. Therefore, its result is the cancellation or failure of in time project delivery. SW costing is done according to size, effort and schedule (time). These parameter has been changed throughout in the development cycle therefore it is difficult to measure exact/actual cost at the starting of the sw development. Actual software costing depends on the right estimated cost of project that should be estimated at early phases of SDLC. This research focus on the methodologies that can help to estimate right costing on the basis of functional requirements of the project during early phases of SW development. A survey is performed that make sure that how software estimation can be done in early stage of software development.
