Software effort and cost estimation has turned out to be the major challenge in IT industries. In this paper, different software effort and cost estimation techniques like algorithmic methods, expert judgment, analogy based estimation and soft computing methods and their various aspects are discussed. Software effort estimation is followed by cost assessment that is useful for both customers an...

Effort estimation is the first of many steps in the software development process that can lead to a successful project’s completion. It is a complex task, that constitutes the basis for all subsequent steps related to planing and management. Effort estimation is also a very important part in agile software development projects. In order to achieve the highest possible levels of accuracy, softwa...

This paper describes an empirical study of effort estimation in agile software development. Estimated effort and actual effort of a 46-iteration project are collected and analyzed. The results show that estimation in agile development is more accurate than that in traditional development even though agile developers still underestimate the effort. However, estimation accuracy is not improved ov...

ÐMany software systems built in recent years have been developed using object-oriented technology and, in some cases, they already need adaptive maintenance in order to satisfy market and customer needs. In most cases, the estimation and prediction of maintenance effort is performed with difficulty due to the lack of metrics and suitable models. In this paper, a model and metrics for estimation...

Test Effort Estimation is an important activity in software development. The test effort can be calculated on the basis of effort cost and time required for testing. Several studies have been done for developing test effort estimation models but to some extent only, most of these models result in erroneous results. So there is a strong need to optimize the efforts estimated. Meta heuristic tech...

One of the most critical tasks during the software development life cycle is that of estimating the effort and time involved in the development of the software product. Estimation may be performed by many ways such as: Expert judgments, Algorithmic effort estimation, Machine learning and Analogy-based estimation. In which Analogy-based software effort estimation is the process of identifying on...

In the field of software engineering, effort estimation plays an essential role. The process of testeffort estimation more important , in order to not exceed the budget of the project. This paperdiscusses one important aspects of this development, which is used in the field of effortestimation in software projects. This commonly used Method for test effort estimation will be...
