I am especially grateful to Timothy Green for affirming the need to have this book published on a tight timeline. Our readers deserve nothing less.

Heartfelt thanks to Amy Stonebraker for her project oversight and to Claire Yee for proficiently managing the submissions phase of this project, facilitating rapid turnaround, and equipping me with information I needed to produce the manuscript.

I would like to thank Bobby Rogers, who took on the task of tech reviewing the manuscript. Bobby carefully and thoughtfully read the entire draft manuscript and made many useful suggestions that have improved the book’s quality.

Many thanks to contributors Tanya Scott, who wrote Chapter 1 and Appendix B of the first edition of this book and revised it for the second edition of this book; Chris Tarnstrom, who wrote the original Appendix A; and Justin Hendrickson, a CISA and consultant who practices in Seattle, for updates of Appendix A and B for this edition. These important texts help readers better understand the CISA certification process and help IS auditors to be more effective in their work. Tanya, Chris, and Justin’s professional auditing experience and insight add considerable value to this book, long after readers become CISA-certified. My vision for this book includes value for aspiring as well as practicing IS auditors; these contributions allow the book to fulfill this vision.

Many thanks to Bill McManus for his great copyediting and further improving readability; Bill made numerous key suggestions for this edition. Much appreciation to MPS Limited for the page layout. Like Olympic athletes, they make hard work look easy.

Special thanks to Poonam Bisht and Janet Walden for overseeing the production of the book and wringing out errors.

Many thanks to my literary agent, Carole Jelen, for diligent assistance during this and other projects. Sincere thanks to Rebecca Steele, my business manager and publicist, for her long-term vision, for keeping me on track, and for photos that she obtained for the manuscript.

Despite having written over 40 books, I have difficulty putting into words my gratitude for my wife Rebekah and daughter Shannon for tolerating my frequent absences (in the home office) while I revised and added content for this third edition. This project could not have been completed without their unfailing support. They both deserve the credit.
