This paper reports results from study conducted to evaluate method estimating software development effort based on cases, points method, by comparing it with expert1 estimates. A system was described brief problem statement detailed model. The gave an estimate that closer actual spent implementing than most estimates made 37 experienced professional developers divided into 11 groups (MRE 0.21 versus MMRE 0.37). support existing claims be successfully effort. They also show combination expert particularly beneficial when estimators lack specific experience application domain technology used.
