Estimation model is key factor to calculate the size of project and in turn estimate the efforts.Based on these efforts project commitment can be provided.However, there is no accurate model which can predict exact size and efforts in new generation projects which are based on agile development methodology.In earlier days of project development methodology were of conventional types where requirements were almost freeze at the start and waterfall model was good to serve the purpose.But in today's scenarios market changes very fast and development needs are changed accordingly so the agile development is need of the era.The user story estimation approach is very much acquainted for agile development and serve the purpose.Estimations are fairly good with the user story approach, also phase delivery life cycle model leverage the advantages of phase wise estimation.To summarize the context, phase wise project lifecycle and phase wise estimation model provides and improved estimation model where the productivity is also based on the actual results of previous projects.
