Producing accurate software effort estimation is essential for effective software project management that remains a considerable challenge to software engineering and software industry in general. Many methods have been proposed to increase the accuracy of estimating the software project size, effort, or cost. However, the primary focus has been on functional requirements FRs. We are convinced that...
Despite improvements in single-task software effort estimation, IT projects routinely exceed estimates. Guidelines for organization-wide estimation can help overcome challenges involving governance, people, processes, and tools.
Accurate software effort estimation has been a challenge for many software practitioners and project managers. Underestimation leads to disruption in the project's estimated cost and delivery. On the other hand, overestimation causes outbidding and financial losses in business. Many software estimation models exist; however, none have been proven to be the best in all situations. In this paper, a...
Software effort prediction is an important task in the software development life cycle. Many models including regression models, machine learning models, algorithmic models, expert judgment and estimation by analogy have been widely used to estimate software effort and cost. In this work, a Tree boost (Stochastic Gradient Boosting) model is put forward to predict software effort based on the Use Case...
Software cost estimation predicts the amount of effort and development time required to build a software system. It is one of the most critical tasks and it helps the software industries to effectively manage their software development process. There are a number of cost estimation models. The most widely used model is Constructive Cost Model (COCOMO). In this paper, the use of back propagation neural...
Accurate software effort estimation is essential for successful project management. To improve the accuracy, a number of estimation techniques have been developed. Among those, Analogy-Based Estimation (ABE) has become one of the mainstreams of effort estimation. In general, ABE infers the effort to accomplish a new project from the efforts of the historical projects which possess similar characteristics...
In this study, an analysis is performed in order to explore whether and how culture and leadership factors have an impact on the accuracy of software effort and cost estimation. A survey on software development projects within government departments in the United Arab Emirates (UAE) was undertaken. A Bayesian Belief Network (BBN) cost estimation model incorporating organizational and intercultural...
The system-level size measures are particularly important in software project management as tasks such as planning and estimating the cost and schedule of software development can be performed more effectively when a size estimate of the entire system is available. However, due to the black-box nature of components, traditional software measures are not adequate as system-level measures for component-based...
