Read the Reviews:
“During a 40-year career in Information Technology I have found one of the most difficult concepts to get agreement or even understanding is ‘How to estimate software development projects.' The number of techniques and their complexity elevate this discipline almost to a mystical art known only by the chosen few who are adept at reading the tea leaves. In this book, Mr. Chemuturi has taken the difficult subject of software estimating and approached it logically, thoroughly and understandably. As an IT practitioner and Project Manager over the years I have estimated and developed hundreds of software projects. This book represents the finest and most lucid exposition on the subject of software estimating that I have ever had the good fortune of reading. It is not a once and done read, it becomes a valuable desk reference for any new software projects where a solid approach to estimating is required. It is the gift that keeps on giving. Use it and benefit from the knowledge and wisdom contained within the pages... I have.” —Robert C Anderson, Director, Process Development and Quality Assurance Computer Aid, Inc. “Effective estimation is one of the most vital success factors of any project, and especially so in the software industry. Yet, many people struggle with how to estimate software projects due to high uncertainty, great complexity, and the pressure to churn out more, faster. In this definitive and much-needed book, Murali Chemuturi offers real-world solutions, explaining all aspects of proper software estimation in an engaging and accessible style. He exposes myths, clears up misconceptions, and offers practical advice on estimating every imaginable kind of software project. This should be on the desk of anyone who manages software projects.” —Jerry Manas, Author of Napoleon on Project Management and Managing the Gray Areas | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
About the Item:
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 well-defined processes, 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. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
