An Empirical Model of Software Size and Work-Effort Estimation for Business Application Software

This paper develops a methodology that produces a more reliable and accurate predictor of software size at an early stage of the systems development process than the more widely known Function Point Methods. In the first stage, Base Product Points (BPP) are computed at a logical level that is independent of information technology. In the second stage, a secondary group of metrics called Enhanced Product Points (EPP) is measured at the physical level.
