This paper describes an empirical study of effort estimation in agile software development. Estimated effort and actual effort of a 46-iteration project are collected and analyzed. The results show that estimation in agile development is more accurate than that in traditional development even though agile developers still underestimate the effort. However, estimation accuracy is not improved ov...

Accurate software cost estimation is a vital task that affects the firm's software investment decisions before committing required resources to that project or bidding for a contract. This study proposes an improved Case-Based Reasoning (CBR) approach integrated with multi-agent technology to retrieve similar projects from multi-organizational distributed datasets. The study explores the possib...

Software project planning and estimation is the most important confront for software developers and researchers. It incorporates estimating the size of the software project to be produced, estimating the effort required, developing initial project schedules, and ultimately, estimating on the whole cost of the project. Numerous empirical explorations have been performed on the existing methods, ...

Software quality and software development productivity have been topics of major interest and concern for the past three decades. The recent rapid growth in the size and complexity of software, and the cost of developing software, has given a greater sense of urgency to finding ways to assure quality of software and bring the cost of developing software under some semblance of control. In this ...

This paper presents a layered model which determines the software metrics in the lower layer it consists of three primitive primary software engineering metrics; they are person-months (PM), function-points (FP), and lines of code (LOC). The middle layer consists of the proposed function point which is obtained by grouping the adjustment factors. The proposed method uses fuzzy logic for quantif...

A variety of Software Sizing approaches have been conjectured in the literature. While many of these approaches have been used for Software Cost Estimation, none were specifically designed for Software Costing. This paper reviews current methods of Software Sizing to determine their suitability for Software Cost Estimation. The approach differs from previous approaches in that it is based on a ...

Project planning is one of the most important activities in software projects. Poor planning often leads to project faults and dramatic outcomes for the project team. If cost and effort are determined pessimistic in software projects, suitable occasions can be missed; whereas optimistic predictions can be caused to some resource losing. Nowadays software project managers should be aware of the ...
