Comparative Study of Different Project Size Estimation Technique for the Development of Software

In SDLC (Software development life cycle model) there are various phase we use to develop the software in that the one is planning phase in this phase we use some estimation technique for estimate the Size, Cost, Effort etc for the software. The main objective of software engineering discipline is to develop the software in systematic and discipline manner as per user requirement. And also the software should deliver in time and in budget. To acquiring this feature is called planning of the software i.e. how much it take time and cost to complete and effort required form development is depend on nature of the software. The objective of this paper is to find out advantages and shortcoming of different Size estimation technique. In this paper we compared all traditional approach for size estimation technique.
