Estimativa de tamanho de software por meio da técnica de análise de pontos de função

Abstract

One of the bigger problem encountered in the process of system development is to complete projects with quality, on time and budgets provided. Having knowledge of what and how much needs to be produced arguably increases the success of the management and successful completion of the systems. Therefore, this study aims to define the concept of software estimation and its applicability in the development process, as a tool to support planning and management systems to increase the quality of the final product. Besides presenting the types of available estimates in the process of estimating system, the paper seeks to identify which are the main techniques for estimating size of software available on the market, its applicability and its main advantages, to assist in understanding the size of the systems to be developed. The paper also presents the definition, operation and advantages of the technique to estimate software size: Function Point Analysis. Finally, we present a case study to demonstrate the applicability of this technique, by obtaining the estimated size of a real system.
