This book is dedicated to my husband, Ron, who is my strictest critic, but my staunchest support, my very best friend, and soul mate. It is also dedicated to my Mom and Dad, who are with me in spirit always. Finally, it is dedicated to Lila, Sammie, Lucy, Baxter, Bonnie, Buford, and Peaches, who have always loved me, no matter what!
My sincere thanks to Chris F. Kemerer and Michael D. Frutiger for their feedback on earlier drafts of this book. Their comments and suggestions have been invaluable. I also thank Rajiv D. Banker and Gordon B. Davis, my PhD co-advisors, for encouraging me to study the software industry and for their wise counsel and advice throughout my academic career.
