Abstract: During the past three decades there had been some significant developments in effort estimation, size of the software, cost estimation methodology. This study describes development in Source Line of Code (SLOC), Function Point Analysis (FPA) and User Case Point Analysis (UCPA). Some of these developments are refinements and experience of earlier methodology. The review identifies SLOC as the basic effort estimation method and Function Point Analysis (FPA) as the technology and platform independence and it`s available from early requirement phase. In the function point analysis users can readily understand about their software and its applications, from the customers and not the technician`s perspective. In use case point had a development with the object oriented method and is a software sizing and estimation based on use case counts called use case points. Other new developments include, bottom up approach, top down approach, algorithmic method, putnam`s model, graphical user interface metrics, cocomo and object metrics to assist the effort estimation in selecting the appropriate model for a specific case. Each of these developments is discussed in detail.
