Enhancement in COCOMO Model Using Function Point Analysis to Increase Effort Estimation

COCOMO is constructive cost model, considered as the most accurate model for effort estimation. Function point is another method to calculate the efforts. Effort estimation is a method to estimate efforts before the development of software. There are many models that measure the efforts accurately. My proposed work is to estimate the efforts using hybrid technique of previous models. The generated result will estimate closer efforts than COCOMO. In this paper, we have presented effort estimation models, COCOMO, Dotty model, Baily- Baisily model, Walston-felix model, Halstead and the proposed one. We have taken 20 projects with defined values of cost drivers. The result shows that the hybrid formula provides more accurate results than the other estimation models. Same dataset is used with 15 cost drivers.
