A clearly written book that is a useful primer for a very complicated set of topics.
--Capers Jones, Chief Scientist Emeritus, Software Productivity Research LLC
Practical Software Estimation brings together today's most valuable tips, techniques, and best practices for accurately estimating software project efforts, costs, and schedules. Written by a leading expert in the field, it addresses the full spectrum of real-world challenges faced by those who must develop reliable estimates.
M. A. Parthasarathy draws on the immense experience of Infosys, one of the world's largest and most respected providers of IT-enabled business solutions, to bring you the only book with detailed guidance on estimating insourced and outsourced software projects, as well as projects that blend both approaches. He demonstrates how to successfully utilize Function Point (FP) methods, the industry's leading estimation model. Then, using real case studies, he systematically identifies pitfalls that can lead to inaccurate estimates--and offers proven solutions.
Coverage includes
How to estimate all types of software projects, including fresh development, reengineering, and maintenance
How to incorporate the impact of core project elements on estimates: scope, environment, experience, and tools
FP analysis from start to finish: data and transaction functions, general system characteristics, and more
FP methods for any platform or business function
Innovative re-estimation methods to track progress
How to quote RFPs and prepare contracts: fixed price, time/material, and project execution lifecycle models
Alternatives to FP: Delphi, COCOMO II, and COSMIC-FFP
How to choose the right estimation tools
Practical Software Estimation is the definitive reference for anyone who must estimate software projects accurately: project and IT managers, individual developers, system designers, architects, executives, consultants, and outsourcers alike.
