The software effort estimation techniques are those which are applied to estimate software efforts. The various software effort estimation models are designed like COCOMO, COCOMO –II etc. It is analyzed that software estimation models are directly proportional to KLOC value. The software efforts are directly depending upon the KLOC value which is hard to estimate. In this review paper, various techniques are analyzed which are used for the KLOC estimation
KLOC, Effort Estimation, COCOMO.
