Software projects often do not meet their scheduling and budgeting targets. Inaccurate estimates are often responsible for this mismatch. This study investigates extant research on factors that affect accuracy of software development effort estimation. The purpose is to synthesize existing knowledge, propose directions for future research, and improve estimation accuracy in practice. A systemat...

Software cost estimation (SCE) remains a complex problem, which continues to attract considerable research at an early stage in the software development process. Researchers have attempted different approaches. Lately, models based on artificial intelligence techniques have been developed. Case base reasoning (CBR) has emerged recently as a promising approach, with comparable accuracy and it is...

A cornerstone of software project management is effort estimation, the process by which effort is forecasted and used as basis to predict costs and allocate resources effectively, so enabling projects to be delivered on time and within budget. Effort estimation is a very complex domain where the relationship between factors is non-deterministic and has an inherently uncertain nature, and where ...

Software Effort estimation is the process of predicting the effort required to develop software project based on incomplete, uncertain and/or noisy input. Researchers have been working on estimation models to predict effort to be spent on a software project, which is still a complex problem. Estimation models derived by researchers are conclusion of studying large number of completed software p...

Context: software development effort estimation is a crucial management task that critically depends on the adopted size measure. Several Functional Size Measurement (FSM) methods have been proposed. COSMIC is considered a 2nd generation FSM method, to differentiate it from Function Point Analysis (FPA) and its variants, considered as 1st generation ones. In the context of Web applications, few...

Accurate estimation of software’s cost isone of the most intricate activity during the software development lifecycle.There are many factors that directly or indirectly affect the development cost of any software and these factors range from the size of the software to the experience of project manager. Calculating and interpreting these factors would be much valuable in software cost estimatio...

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...

Global Software Development, also known as Distributed Software Development, is originally an outsourcing technique in which the development teams hailing from diverse cultural backgrounds and located at distant remote locations participate in the software development efforts and provide their services through a tightly coupled computer networks like Internet. Accurate software cost and effort ...

Effective cost estimation is the most challenging activity in software development. Software cost estimation is not an exact science. Cost estimation process involves a series of systematic steps that provide estimate with acceptable risk. Some prevalent LOC based models areBailey Basili model, Alaa F. Sheta G.E. Model, and Alaa F. Sheta, Model 2 [1] .Two new models, based on fuzzy logic sizing...

Software cost estimation is the process of predicting the effort required to develop a software system. The basic input for the software cost estimation is coding size and set of cost drivers, the output is Effort in terms of Person-Months (PM’s). Here, the use of support vector regression (SVR) has been proposed for the estimation of software project effort. We have used the COCOMO dataset and...
