Project Failure is the major problem undergoing nowadays as seen by software project managers. Imprecision of the estimation is the reason for this problem. As software grew in size and importance it also grew in complexity, making it very difficult to accurately predict the cost of software development. This was the dilemma in past years. The greatest pitfall of software industry was the fast ...

Software development effort estimation is the process of calculating the effort required to develop or maintain software based on the input, which is partial, tentative and/or strident. Efficient project estimation is one of the most difficult and significant activities in project development. “Effort Estimation” is supposed to be fateful because of infrequency, uniqueness, underestimation bias...

Despite the predictive performance of AnalogyBased Estimation (ABE) in generating better effort estimates, there is no consensus on: (1) how to predetermine the appropriate number of analogies, (2) which adjustment technique produces better estimates. Yet, there is no prior works attempted to optimize both number of analogies and feature distance weights for each test project. Perhaps rather th...

A usual activity performed to ensure software reliability is functional testing, where organizations can allocate teams exclusively for testing. With tight schedules and limited resources, test managers shall be able to estimate the effort required to execute the test suites requested by their clients (usually development teams), and also to estimate its capacity for attending the requests. Sev...

The importance of Software Cost Estimation at the early stages of the development life cycle is clearly portrayed by the utilization of several algorithmic and artificial intelligence models and methods, appeared so far in the literature. Despite the several comparison studies, there seems to be a discrepancy in choosing the best prediction technique between them. Additionally, the large variat...

A number of software cost estimation methods have been presented in literature over the past decades. Analogy based estimation (ABE), which is essentially a case based reasoning (CBR) approach, is one of the most popular techni...

The construction of software cost estimation models remains an active topic of research. The basic premise of cost modelling is that a historical database of software project cost data can be used to develop a quantitative model to predict the cost of future projects. One of the difficulties faced by workers in this area is that many of these historical databases contain substantial amounts of ...

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...

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...
