Executive Summary

Even though there are a number of software size and effort measurement methods proposed in this paper, they are not widely adopted in the practice. According to this paper, only 30% of software companies use measurement, mostly as a method for additional validation. In order to determine whether the objective metric approach can give results of the same quality or better than the estimates relying on work breakdown and expert judgment, the authors have validated several standard functional measurement and analysis methods (IFPUG, NESMA, Mark II, COSMIC, and use case points), on the selected set of small and medium size real-world web based projects at CMMI level 2.
