TTI was started in 1984 by Bill Bonnstetter, with the help of his son and collaborator, Dave Bonnstetter. Bill is considered one of the pioneers in the assessment industry because of his significant contributions to the research and study of human behavior. He was the first to computerize the DISC (Dominance, Influence, Steadiness, Compliant) assessment, making reports available via his patented Internet Delivery Service® (IDS) . He was also the first to produce a computerized values assessment based on Eduard Spranger’s personality model. Bill is responsible for the three patents TTI holds, one each for TTI’s ground-breaking job benchmarking process, its internet delivery system, and employee success prediction system. Bill is a 2012 Edison Award nominee, which recognizes and honors innovation and excellence in the development, marketing and launch of new products and service. He holds a bachelor’s degree in business and marketing as well as a master’s degree in business education. He is the author of If I Knew Then, and The Universal Language DISC, which has sold more than 30,000 copies and is now in its sixth edition, as well as articles for the Harvard Business Review, and has been featured in books such as My Dear Franchisees by Ann Andrews, CSP, and Carl Davies, Conversations for Change by Shawn Kent Hayashi.
