Chapter 5 of Stutzke’s book discusses judgment-based estimation techniques and provides background on some of the math described in this chapter. Chapters 8 and 9 de-scribe additional size estimation techniques including Use Case Points, Application Points, Web Objects, and simplified function point techniques. Stutzke also discusses size estimation on COTS (commercial off the shelf) projects. Chapter 12 describes ap-proaches to effort allocation that are based on Cocomo 81 and Cocomo II. Chapters 15 and 23 of Stutzke’s book focuses on detailed cost estimation issues. Cost estimation and other cost-related issues are a major focus of Stutzke’s book, and various cost-related tips are sprinkled throughout. Sections 12.1 and 12.2 discuss the relationships between effort, duration, and staff availability. Chapter 20 describes how to create a WBS. Ap-pendix C of Stutzke’s book contains a summary of measures of estimation accuracy.

Boehm, Barry, et al. Software Cost Estimation with Cocomo II, Reading, Mass.: Addison Wesley, 2000. This book is the definitive description of Cocomo II. The book’s size is daunting, but it describes the basic Cocomo model within the first 80 pages, including detailed definitions of the effort multipliers and scaling factors discussed in this chapter and how Cocomo II accounts for diseconomies of scale. The rest of the book describes extensions of the model. Boehm was the first to popularize the Cone of Uncertainty (he calls it a funnel curve). This book contains his most current description of the phenome-non. Appendix A of Boehm’s book describes effort and schedule breakdowns for water-fall projects, MBASE projects, and Rational Unified Process projects. Table A.10 (which is actually six tables) provides detailed breakdowns of effort and schedule across different activities. Appendix E of Boehm’s book contains a checklist that’s useful for precisely defining what constitutes a "line of code."

This book describes Putnam’s estimation method including how it addresses diseconomies of scale. I like Putnam’s model because it contains few control knobs and works best when it is cali-brated with historical data. The book is mathematically oriented, so it can be slow going. Putnam and Myers also provide numerous useful rules of thumb for planning. The over-all context of Putnam and Myers’ book is a detailed, mathematical explanation of Put-nam’s estimation model.
