Effort estimation is a key factor for software project success, defined as delivering software of agreed quality and functionality within schedule and budget. Traditionally, effort estimation has been used for planning and tracking project resources. Effort estimation methods founded on those goals typically focus on providing exact estimates and usually do not support objectives that have rece...

Software cost estimation is an important phase in software development. It predicts the amount of effort and development time required to build a software system. It is one of the most critical tasks and an accurate estimate provides a strong base to the development procedure. There are many cost estimation models for the estimation of the software. COCOMO model is the basic model. In this pape...

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 ...

Development effort is an undeniable part of the project management which considerably influences the success of project. Inaccurate and unreliable estimation of effort can easily lead to the failure of project. Due to the special specifications, accurate estimation of effort in the software projects is a vital management activity that must be carefully done to avoid from the unforeseen results....

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 several classes of software cost estimation models and techniques: parametric models, expertise-based techniques, learning-oriented techniques, dynamics-based models, regression-based models, and composite-Bayesian techniques for integrating expertisebased and regression-based models. Experience to date indicates that neural-net and dynamics-based techniques are less matur...

This paper examines how a team of software professionals goes about estimating the effort of a software project using a judgment-based, bottom-up estimation approach. By employing a social practice perspective that highlights the distributed character of expertise and conceives actions as mediated by cultural tools, the paper analyzes the interactional process through which the estimation tasks...
