Acknowledgments

Chris and Robbin want to thank their families for all their support with this book and for providing us with the time and space to get the job done. In addition, Scrum.org especially has been instrumental in providing an environment of inspection and adaption, envisioning, and knowledge sharing about Professional Scrum product ownership.

Another big thank you to everyone who took the time to review our book and provide invaluable feedback, especially Kurt Bittner, Gillian Lee, Tommy Norman, and Kent J. McDonald.

Finally, we want to thank all our friends, peers, and students. We thank all the people who joined our training courses, asked tough questions, and motivated us to put our story on paper. We also thank all the great product folks from the Value Maximizers community who joined our talks and workshops and shared their experiences and stories.
