Tang Zi-nan, Fengdi Shu · Jisuanji gongcheng yu sheji · 2008
Software development effort estimation can support many requirements and tasks which are involved in organization decision- making and project management activities.Based on those multi-purposes,an lOP-model for effort estimation is introduced.The model parameters are extended from COCOMO (constructive cost model)Ⅱand are calibrated by regression analysis from the latest domestic and international software repository,lOP-model adopts a uniform framework and describes effort-and-size-relationship on three levels ofindustry,organization and project,lts result in each level could explain problems of different hierarchies which software organizations and users focus on,such as:project bidding,multiple project management in the same organization and specific project management. Some sample uses of IOP-model are given at the end.
