This thorough revision of the first edition was only possible with the collaboration and support of my family, friends, and colleagues. I want to thank the team at Packt for responding to reader feedback and taking the project from start to finish. Chris Nelson was a thorough editor and provided constructive advice. I want to thank my clients for the opportunity to do such exciting work that often offered valuable inspiration for this book.

Most important, however, has been the unrelenting patience and support of Mariana. To her and Bastian, who make it all worthwhile, I dedicate this book.
