Comparison of COSYSMO Model with Different Software Cost Estimation Techniques

Cost Estimation of any software is process of evaluating the estimating cost and effort which is must necessary to build any software system or project for increasing the output. The basic input is the cost drivers set and the size of code and the output is the effort which is calculated in terms of Person-Months (PM's). To estimate cost for software is the main portions of any project type and right estimation of cost for the software will help in completing project in of time and budget. Proper cost estimation of a software project is highly needed to avoid any risk failure. So, there is a strong need to calculate the project's cost annually and compare it to the other techniques. This paper deals with the analysis and comparison of COCOMO model of Boehm's and COSYSMO model of Valerdi's through the help of formulae's and an online tool present at the CSSE website. For this we have used the COCOMO dataset and it has been observed that COSYSMO model works better than the COCOMO model in every aspect.
