Accurate Software Size Estimation Using the Updated Function Point Analysis Model

2 Abstract: In this paper; a new Function Point Analysis model has been proposed. In this proposed model, a new general system characteristic is added. The expert user programming also affects the size of software. By including it in the list of general system characteristics, it creates a provision for taking end user facilities into account, while estimating the size of a project. It is clear that proposed FPA provides more accurate size estimates and it will narrow the gap between size estimated and actual size. This will result in more accurate effort and cost estimates, which ultimately results in increased productivity and proper staffing, planning and scheduling. This document describes the Function point analysis which measures software by quantifying the functionality the software provides to the user based primarily on logical design. Here in this Function Point Analysis model has been proposed which creates a provision for taking end user facilities into account, while estimating the size of a project. This paper comprises of four sections including the present one which describes the goal of this paper. Section II shows research based papers which illustrates related work in function point analysis. Section III gives a brief introduction regarding proposed model and experimental result. And at last section IV describe the conclusion and references. .
