Accurate estimating is one of the most important activities in the field of software project management. Different aspects of software projects must be estimated among which time and effort are of significant importance to efficient project planning. Due to complexity of software projects and lack of information at the early stages of project, reliable effort estimation is a challenging issue. ...

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 ...

Reliable effort estimation remains an ongoing challenge to software engineers. Accurate effort estimation is the state of art of software engineering, effort estimation of software is the preliminary phase between the client and the business enterprise. The relationship between the client and the business enterprise begins with the estimation of the software. The credibility of the client to th...

Estimating the effort of software development is fraught with difficulties, and it is clear that effort should be invested in improving the accuracy and the reliability (consistency) of effort estimates, as well as the assessment of estimate uncertainty. However, it is less clear where to target such improvement efforts. We discuss the degree to which it is feasible to improve the expertise of ...

It is well documented that the software industry suffers from frequent cost overruns. A contributing factor is, we believe, the imprecise estimation terminology in use. A lack of clarity and precision in the use of estimation terms reduces the interpretability of estimation accuracy results, makes the communication of estimates difficult, and lowers the learning possibilities. This paper report...

Discussions with software developers from a number of business organisations were targeted at the effect of estimation practices on the success or failure of some of the software development projects with which they had been involved. Several important estimation topics were also covered in a questionnaire. Our results show that for only one-third of the projects were the project managers invol...
