Adrian and Chester Elton's flagship book, The Carrot Principle, was based on a 200,000 person study from 1996-2006. The second edition published in 2009 included a 2008 global survey of 10,000 people in 13 countries. The results of these studies revealed the surprising advantages of recognition on employee performance, including its effects on morale, productivity and return on equity. Their upcoming collaboration, The Orange Revolution (publish date September 2010), is a follow up based on a 350,000 manager and employee survey on the power of teamwork.

Adrian was born in Burton, England and educated in the United Kingdom, Canada, and the United States. Adrian earned a Master’s degree in Strategic Communication and Leadership from Seton Hall University.
