For estimating software, system size is the main parameter of the system development effort. It affects substantially on accurate estimation of effort of development. The predictive object point (POPs) input gives an estimate of the size of the software for which the estimation is required. POPs are a metric suitable for estimating the size of object oriented software, based on the behaviors that each class is delivering to the system along with top level inputs describing the structure of a system. However there is no real mapping of Source Lines of Code (SLOC) to POPs exists. This paper is an attempt to map the predictive object point Metrics with software size which may help in further prediction of effort. This may also help in estimation of cost as well as schedule measurement of an 00 system. The proposed method of mapping between POP and software size has been empirically investigated. KLOC has been estimated in terms of EKLOC through POP count using the linear regression equation. The results are presented here to show that how POP Count may be mapped to corresponding software size (KLOC) of an object oriented system.

Different effort estimation techniques exist for sizing software systems but none is directly applicable to object-oriented software. Although many researchers worked for size and thus effort estimation but still the problem not resolved fully. Different existing estimation techniques works specifically for specific development environment. PRICE systems has developed the predictive object point (POP) metric for predicting effort required for developing an object oriented software system and is based on the counting scheme of function point (FP) method. Though it was an interesting theoretical development but could not gain sufficient recognition from practitioners to be used on a regular basis due to lack of an easy to use support tool and too much complicated formulations. In this paper we tried to simplify the POP calculation. The POP count formula suggested by PRICE system has been modified for estimating the effort. An easy to use support tool to automate the counting method has been prepared. The refined POP count formula and preliminary results of its application in an industrial environment are presented and discussed here for validation of the suggested modification or simplification in formula.
