Graham studied Agriculture and Accounting at university and started his own accounting practice in 1996. He discovered and implemented Theory of Constraints thinking into the business about 10 years later. He has implemented TOC into many client businesses and taught a 6-day Theory of Constraints Thinking Tools course internationally.
Graham completed a Master of Commerce degree in 2020, applying TOC thinking to the traditional budgeting process to find out why people behave the way they do around budgeting and how it causes waste.
Graham sold his accounting practice in 2021 and wrote a book called “Practice Makes Profit” which tells stories about applying TOC to business. The book and the continual use of the disciplined TOC Thinking Tools has led to directorships, problem-solving workshops and various coaching roles, including developing the Senior Leadership Team at a software company.
