Goldratt Research Labs

Goldratt Research Labs (GRL) was founded in 2007 by Dr. Alan Barnard, on request of Dr. Eli Goldratt, the creator of Theory of Constraints (TOC), to create a research organization that would be a spearhead for new Theory of Constraints based research and development to help accelerate and test the ever growing TOC body of knowledge.

The Odyssey Program

When was the last time you invested a full day into analyzing your own life - looking at what you really want or what and how you can achieve it?. The Odyssey Program is aimed at helping attendees understand why we all sometimes resist changes that we probably know will be good for us, and/or make changes that end up being bad for us and our organizations; and how to prevent these avoidable decision mistakes on any problem or decision they are currently facing at work or at home. The program follows five simple steps, using a simplified version of the Theory of Constraints Thinking Processes called the Change Matrix Cloud Process, designed specifically to help us overcome the five most common decision mistakes we make when dealing with chronic problems and/or stressful expectation gaps and decisions at work and at home.  Past attendees say that the Odyssey program really does its name justice. It offers attendees a journey of personal discovery to help find and overcome their own bottleneck - the limiting assumptions that can cause us to make and often repeat bad decisions which in turn limit or delay us from achieving more of our personal and professional goals.
