Analysis of Cost Size and Effort Estimation Models for Software System

Abstract
Software effort and cost estimation is a very crucial activity. If the estimation is done precisely, it results in decreasing error rate. Estimation process represents the reality of project’s progress. It avoids cost/budget or schedule overruns. This paper proposes a survey of the most popular cost estimation models. It will propose the pros and cons of every model. It will help future researchers up to a great deal and they will be able to develop more efficient model for the accurate cost estimation. This process is quite simple which takes a few inputs. This assessment framework helps inexperienced team improve project tracking and estimation. Much work can be carried on it. Various COCOMO parameters can be adjusted. Further work can be carried on learning based methods which apply weights to calculation of each software module based on priorities and criticalities. A good estimate should have amount of granularity so it can be explained. Since the effort invested in a project is one of the most important and most analyzed variables.
