Abstract
Intermediate COCOMO Model computes effortas a function of program size and a set of cost drivers. Effortadjustment factor (EAF) is calculated using 15 costdrivers. EAF is an important significant factor in computingsoftware development effort. We have taken one delivereddevelopment project of size of 479 function points andplanned for 917 Person days of SEI CMM Level 5 “Excellent”Company as a case study to analyze the EAF. We haveempirically validated the cost driver model for IntermediateCOCOMMO using this projects data. Validation has beendone by using other two development projects data of ExcellentCompany. From our analysis, we have found that costdrivers defined ratings need to be revisited for the projectsof size less than 10 Person months. We have come out withratings for some cost drivers where earlier it was not defined.This approach helps the project managers to anticipateand estimate the efforts for development projects preferablyless than 10 Person months. We have achieved approximately30% improvement in effort variance by followingthis approach.
