Reliable and accurate estimation of software has always been a matter of concern for industry and academia. Numerous estimation models have been proposed by researchers, but no model is suitable for all types of datasets and environments. Since the motive of estimation model is to minimize the gap between actual and estimated effort, the effort estimation process can be viewed as an optimizatio...

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...

Effective software effort estimation is one of the biggest challenges in software engineering. One of these challenges occurs when it is required to estimate software effort in the early stages of the software life cycle, as software requirements in this stage are usually incomplete. As Unified Modeling Language (UML) model became more prominent in software requirements and design processes, so...

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 ...

Academia and practitioners confirm that software project effort prediction is crucial for an accurate software project management. However, software development effort estimation is uncertain by nature. Literature has developed methods to improve estimation correctness, using artificial intelligence techniques in many cases. Following this path, this paper presents SEffEst, a framework based on...

predicting the effort of a successful project has been a major problem for software engineers the significance of which has led to extensive investigation in this area. One of the main objectives of software engineering society is the development of useful models to predict the costs of software product development. The absence of these activities before starting the project will lead to variou...

Globalization is adding more dimensions to software effort estimation process. The notions of leadership and culture carry with them highly variable assumptions, and thus, must be explicitly modeled. A new model that incorporates leadership and culture is proposed, elaborated and validated. A survey was undertaken to determine the impact of culture and its effect on the software development pro...

Software Cost Estimation can be described as the process of predicting the most realistic effort required to complete a software project. Due to the strong relationship of accurate effort estimations with many crucial project management activities, the research community has been focused on the development and application of a vast variety of methods and models trying to improve the estimation ...

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...
