Book Description
Almost every software project begins with the utterances, “What will this cost?” and “When will this project be done?” Once those words are spoken, project stakeholders begin to wrestle with how to produce an estimate. Accurately estimating the cost or time to complete a software project is a serious problem for many software engineers, developers and project managers who struggle with costs running double original estimates, putting their careers at risk. It is reported that nearly 50% of all software projects are shelved and that one of the major causes is poor estimation practices. If developing software for internal use, poor estimates can represent a significant drain on corporate profits. Worldwide growth in the number of companies specializing in the development of software for use by other companies is staggering. India alone has nearly 20,000 such companies. Intense competition has led to an increased demand for fixed-bid pricing in client/vendor relationships, and has made effective cost estimation even more important and, in many cases, critical to a firm's survival. There are many methods of estimation. Each method has its strengths and weaknesses, proponents and opponents. Knowing how and which one to use on a given project is key to developing acceptable estimates for either internal or external projects.Software Estimation Best Practices, Tools, & Techniques covers all facets of software estimation. It provides a detailed explanation of the various methods for estimating software size, development effort, cost, and schedule, including a comprehensive explanation of Test Effort Estimation. Emphasizing that software estimation should be based on a well-defined process, it presents software estimation best practices and shows how to avoid common pitfalls. This guide offers direction on which methods are most appropriate for each of the different project types commonly executed in the software development space and criteria for selecting software estimation tools. This comprehensive desk reference explains software estimation from scratch to help the beginner and features advanced techniques for more experienced estimators. It details project scheduling, including resource leveling and the concept of productivity, as applicable to software estimators, demonstrating the many benefits of moving from the current macro-productivity approach to a micro-productivity approach in software estimation. Software Estimation Best Practices, Tools, & Techniques: A Complete Guide for Software Project Estimators caters to the needs of all software project stakeholders, from novice to expert. It provides the valuable guidance needed to estimate the cost and time required to complete software projects within a reasonable margin of error for effective software development.

In Software Project Estimation, author Dimitre Dimitrov extrapolates upon the most crucial steps in accurately and meaningfully forecasting the timeline and specs of promised deliverables to clients. A client’s positive experience with project delivery and implementation is a software organization’s calling card in the industry. The lifespan of a software project—from ideation to final installation—introduces dozens of potential pitfalls for a company’s track record, earnings, and overall team morale. However, these “pitfalls” are also opportunities to showcase strengths and to improve an organization’s product quality, and it all starts with project estimation. Reliable forecasting continues to present a challenge to even the most veteran teams and software development organizations. Dimitrov sets out to ease these common difficulties with invaluable methodology improvements and helpful visuals from his years of industry experience. Project managers—through harnessing the power of hard data and statistics—have a new world of impactful forecasting at their fingertips. This approach brings security, predictability, and motivation within the team, while simultaneously greatly benefiting client trust and relationships. Software Project Estimation clarifies the common misunderstandings that materialize between making a promise, making a plan, and building a forecast backed by data. Learn how to create an intelligent software project forecast and use it to make timely decisions, apply measured project control, and confidently steer your ship toward your goals with Software Project Estimation. What You Will Learn Concepts related to software estimation, forecasting, and project control Ways in which you can positively affect the relationships among team members working on a software delivery project How to apply this forecasting model, within both agile and waterfall teams who have adopted sound engineering practices Who This Book is For This book is directly relevant to the roles of scrum masters and project managers, and provides practical tools for intelligent project control.

Book Description
"Software Cost Estimation and Sizing Methods: Issues and Guidelines recommends an approach to improving the utility and accuracy of software cost estimates by exposing uncertainty (in understanding the project) and reducing the risks associated with developing the estimates. The approach focuses on characteristics of the estimation process (such as which methods and models are most appropriate for a given situation) and the nature of the data used (such as software size). It describes risks in each of these factors in terms of symptoms and warning signs, and mitigation strategies for each." "The techniques described in this book are based on a literature review and on analysis of software estimation and risk, in addition to general lessons and guidance adapted from selected programs." "This book should be of particular interest to those organizations or agencies that use software estimates in the planning, budgeting, developing, or purchasing of software-intensive systems. It should also be of value to those involved in research and analysis of estimation models and techniques."--BOOK JACKET.
