چکیده

This paper presents the effect of ‘schedule compression’ on software project management effort using COCOMO II (Constructive Cost Model II), considering projects which require more than 25 percent of compression in their schedule. At present, COCOMO II provides a cost driver for applying the effect of schedule compression or expansion on project effort. Its maximum allowed compression is 25 percent due to its exponential effect on effort. This research study is based on 15 industry projects and consists of two parts. In first part, the Compression Ratio (CR) is calculated using actual and estimated project schedules. CR is the schedule compression percentage that was applied in actual which is compared with rated schedule compression percentage to find schedule estimation accuracy. In the second part, a new rating level is derived to cover projects which provide schedule compression higher than 25 percent.

Effect of Schedule Compression on Project Effort

Schedule pressure is often faced by project managers and software developers who want to quickly deploy information systems. Typical strategies to compress project time scales might include adding more staff/personnel, investing in development tools, improving hardware, or improving development methods. The tradeoff between cost, schedule, and performance is one of the most important analyses p...

An Improved COCOMO based Model to Estimate the Effort of Software Projects

One of important aspects of software projects is estimating the cost and time required to develop projects. Nowadays, this issue has become one of the key concerns of project managers. Accurate estimation of essential effort to produce and develop software is heavily effective on success or failure of software projects and it is highly regarded as a vital factor. Failure to achieve convincing a...

Modeling Software Defect Introduction

In software estimation, it is important to recognize the strong relationships between Cost, Schedule and Quality. They form three sides of the same triangle. Beyond a certain point (the "Quality is Free" point), it is difficult to increase the quality without increasing either the cost or schedule or both for the software under development. Similarly, development schedule cannot be drastically ...

Estimation of f-COCOMO Model Parameters Using Optimization Techniques

The COCOMO Model is well known as the currently predominate model for software cost estimation. It allows one to work from linguistic variables to estimate software project effort and schedule. This basis in linguistic variables encourages research of the COCOMO Model as a fuzzy system. As is known in fuzzy circles and is shown here, fuzzy arithmetic based on the popular fuzzy extension princip...

A Multi-objective optimization model for project scheduling with time-varying resource requirements and capacities

Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...
