"A-ha! Performance is a step-by-step manual for achieving collective goals while fostering self-determination. I will be recommending this book to any manager whom I coach or advise and who wants to be more effective, and I will be reading and re-reading it to learn more about how to improve my own relationships while getting more of what I want at work and at home."
