Software engineering is the discipline which paves the road map for the development of software within the given schedule and effort with the desired quality. The process begins with estimating the size, effort and time required for the development of the software and ends with the product. In most existing research on the effort estimation, the Function Point Analysis (FPA) method is used to e...

Expert judgment for software effort estimation is oriented toward direct evidences that refer to actual effort of similar projects or activities through experts’ experiences. However, the availability of direct evidences implies the requirement of suitable experts together with past data. The circumstantial-evidence-based judgment proposed in this paper focuses on the development experiences de...

Many cost estimation models have been proposed over the last three decades. In this study, we investigate fuzzy ID3 decision tree as a method for software effort estimation. Fuzzy ID software effort estimation model is designed by incorporating the principles of ID3 decision tree and the concepts of the fuzzy settheoretic; permitting the model to handle uncertain and imprecise data when present...

One of the greatest challenges for software developers is forecasting the development effort for a software system for the last decades. The capability to provide a good estimation on software development efforts is necessitated by the project managers. Software effort estimation model divided into two main categories: algorithmic and nonalgorithmic. These models too have difficulty in modeling...

Estimating the cost of software is a complex process for almost all engineering companies. Uncertainties about development method, design, estimation process, data, and processing affect the accuracy of estimation. Underestimation results in fewer resources being committed than the project really needs, an unrealistic schedule, and low quality outputs. On the other hand, overestimation wastes r...

Calibration, has been .found to be difficult in practice. Wide experience in using the estimation model is necessary; experience which the beginner naturally lacks. This paper indicates why it is important to calibrate a model and how the inexperienced user can be helped by an expert system. In addition, the development of, and experience with, the prototype of an expert system are described. T...

Estimating the cost of software is a fundamental and difficult process in information technology (IT) industry. Underestimation causes assigning fewer resources than the project needs and setting an unrealistic schedule. On the other hand, overestimation results in waste of resources and low customer satisfaction. It is clear that, software projects can be prioritized efficiently and resources ...

Software undergoes changes at all stages of the software development process. Accepting too many changes will cause expense and delay and rejecting the changes may cause customer dissatisfaction. One of the inputs that help the software project management to decide whether to accept or reject the changes is by having a reliable estimation of the change effort. From a software development perspe...

Software Effort Estimation process is one the most important process in software project management. The importance of software in our daily lives is increasing with every passing day which has resulted in increase in the complexity of softwares. In order to manage software development projects with varying levels of complexity accurate software effort estimations play a pivotal role. This rese...
