Estimation of Project Size Using User Stories

There exist no concrete models for project size estimation in agile, contrary to traditional projects. In agile, contrasting approaches like standard component estimation, wideband-Delphi or expert consensus and function points technique do not proof much workable for early estimation of size, cost and duration due to uncertain initial requirements. Estimation in agile projects is important regardless of the immature nature of the requirements, on which they work. Next is the translation of effort estimates to project size or vice versa, which is equally important. Technique researched in this paper follows the user stories, which get us most possible accurate estimates. Number of story points with a story matter as well for correct size of story. There are certain specific metrics contained in a story which help in identification of its size and reliability. These factors, in weight age of story point are used to calculate sizing of an agile project.
