Software Sizing, Estimation, and Risk Management: When Performance is Measured Performance Improves ReviewManaging the Black Hole: The Executive's Guide to Software Project Risk
Many of us in the software business have developed careful estimates for software projects only to be told by management to "cut it by 1/3" - this book explores how to overcome this all too common challenge. Dan Galorath has done a great job of explaining the SCIENCE of software cost estimating. This book is a must read for anyone serious about software project success!Software Sizing, Estimation, and Risk Management: When Performance is Measured Performance Improves OverviewTo achieve consistent software project success under the pressures of today's software development environment, software organizations require achievable plans including viable estimates of schedule, resources, and risks.To estimate realistically, you must understand how to apply sound estimation processes, tools, and data. Software Sizing, Estimation, and Risk Management: When Performance is Measured Performance Improves is a practical, hands-on discussion of the software estimation, planning, and control process.This includes critical factors that impact estimates, methods for selecting and applying appropriate measures to projects, proper software sizing, and processes to identify and manage risk. The authors use their expertise in sizing, estimation, process engineering, and risk management to clearly demonstrate problems that make many estimates crumble and solutions that provide successful project plans. The book offers insight not available anywhere else, enabling you to recognize and avoid downstream impacts resulting from poor estimates.

Software Estimation Best Practices, Tools & Techniques: A Complete Guide for Software Project Estimators ReviewMurali Chemuturi has written an excellent book that provides a nice overview of both the philosophy and practices of software estimation. In it, he covers the theories and practical realities of estimating software development projects in a simple to read, and easy to understand writing style. Software Estimation provides an excellent summary of various methods of software sizing and covers the pros & cons of each, including an excellent primer on Function Point Analysis. It also includes a very helpful review of Software Size Units, which is the latest way to think about the overall size of a software project taking into account both data and process. SSU seeks to overcome much of the difficulty and ambiguity of trying to count "points" needed for FPA.
One of my personal pet peeves is when developers do not include adequate effort in their estimates for test preparation and the overall testing effort. The book covers this area well and includes an excellent overview of incorporating testing into all your estimates, plus it explains multiple ways to help you do it. Since this is a significant area for me in my work, I have read this section over several times and have already incorporated many of the concepts and metrics covered in this book into my projects.
The only area that is not thoroughly covered in this book is how to estimate using iterative or Agile methodologies, as it tends to focus on the traditional software lifecycle process. However, there is still more than enough valuable information in this excellent book. Chemuturi's book is within easy reach on my desk, and is often stashed in my briefcase. It has easily become my bible for all things related to estimating software application development projects. It is a great value and should become part of any software development manager's toolkit.
