In the process of software project development life cycle, software effort estimation is the important process. The effort estimation affects the success of software projects whether the designers estimate the projects improperly. Normally, software is grown in size and complexity, it is very difficult to precisely known the cost of software development. The main challenging fact of this effort estimation is the software industry was the fast-changing nature of software development. In this paper assessed the several classes of software effort estimation models and techniques. This paper overviews a research study comparing the different estimation techniques that can be helpful to the information technology firms, researchers and software developers that use information technology in the processes such as budgeting and decision-making processes.
