A variety of Software Sizing approaches have been conjectured in the literature. While many of these approaches have been used for Software Cost Estimation, none were specifically designed for Software Costing. This paper reviews current methods of Software Sizing to determine their suitability for Software Cost Estimation. The approach differs from previous approaches in that it is based on a ...

This paper summarizes estimation knowledge through a review of surveys on software effort estimation. Main findings were that: (1) Most projects (60-80%) encounter effort and/or schedule overruns. The overruns, however, seem to be lower than the overruns reported by some consultancy companies. For example, Standish Group’s ‘Chaos Report’ describes an average cost overrun of 89%, which is much h...

The object-oriented technological evolution involving the software industry induces changes in the managerial and organizational models for the software-houses. One of the critical issue for software producers is the cost estimation and control. The research described in this paper is aimed to verify the inadequacy of traditional software cost estimation models and to define an innovative model...

The importance of Software Cost Estimation at the early stages of the development life cycle is clearly portrayed by the utilization of several algorithmic and artificial intelligence models and methods, appeared so far in the literature. Despite the several comparison studies, there seems to be a discrepancy in choosing the best prediction technique between them. Additionally, the large variat...
