Software Cost Estimation Using Expert Judgement, COCOMO and Function Points

Abstract

The accurate software cost estimation is a critical factor in the success of software projects. Multiple method has been proposed to estimate the cost and the size of the software projects. These cost estimation methods have their advantages and disadvantages, selecting the right method is important to get accurate estimations. However, determining which method is the right one is difficult. In this paper we aim to explore the different cost estimation methods to help organizations in determining which of these methods is the most suitable and for what types of projects. This paper presents Software Cost Estimation Using Expert Judgement, COCOMO and Function Points: A Comparative Study. We look at the following methods to estimate the software cost: Expert Judgement, COCOMO and Function Points. Then through a case study we compare the estimations of these three methods to the actual cost of the software development.
