Cost overrun of software projects is major cause of their failures. In order to facilitate accurate software cost estimation, there are several metrics, tools and datasets. In this paper, we evaluate and compare different metrics and datasets in terms of similarities and differences of involved software attributes. These metrics forecast project cost estimations based on different software attr...

There exist numerous sophisticated models and methods for estimating the size, cost and schedule of software projects. However, the ability to accurately predict the software cost of web based software for agile software projects is still dubious. The most appropriate web based software cost estimation in an agile software development environment is a big problem due to varying levels of custom...

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. ...

One of important aspects of software projects is estimating the cost and time required to develop projects. Nowadays, this issue has become one of the key concerns of project managers. Accurate estimation of essential effort to produce and develop software is heavily effective on success or failure of software projects and it is highly regarded as a vital factor. Failure to achieve convincing a...

One important problem with software development projects is to get an early and nevertheless accurate estimation of the software development costs. In the literature various methods have been developed for this purpose. The most popular examples are Boehm's COCOMO , Albrecht's function-point method or Sneed's object-point method . The two last-named methods are based on early results of the ana...

In the software development process, effort distribution based on phase is an important but often a neglected aspect of software cost estimation. Insufficient phase effort distribution study is the primary reason of poor software effort estimation. This paper provides the results of an empirical study on phase effort distribution based on 2956 projects. The software development process is divid...
