David Hodes
Managing Director
BSc Mech. Eng ACGI

David Hodes, the founder of the TOC Centre of Australia (TOCCA), is a qualified System Thinker and Practitioner. He was awarded a National Engineering Scholarship in the UK and attended Imperial College in London, where he graduated with a BSc Mechanical Engineering.

David first came across Goldratt’s Theory of Constraints (TOC) when working as the Managing Director of Africa’s largest commercial refrigeration company.  He knew there had to be a way to meet market demands and deadlines, without continually subjecting his workforce to the intensive work pressure (and accompanying burnout) that had become the norm in their industry.  It was a productivity issue, so he approached the National Productivity Institute (NPI) and they suggested the TOC approach. 

David liked the sound of TOC – it made instinctive sense to him – but the CEO opposed it.  How could a bunch of outsiders (the NPI) tell them how to run a business that they had been running ‘successfully’ for 30 years?  But David was sold on TOC.  He decided to put his money where his mouth was and persuaded the CEO to agree to pilot test the TOC approach, on condition that, if the project failed, not only would David lose his job, he would also personally foot the NPI’s (hefty) bill!

The pilot selected was the complete refurbishment of all of the industrial cold rooms, refrigerators and freezers in an extremely large supermarket.  Hodes and the NPI used Critical Chain, the TOC approach to Project Management, to run the project.  The results were spectacular – the project, expected to take 70 days, was brought in 26 days early!  Hodes was so impressed that he promptly resigned his job, immersed himself in the study of TOC and its methods, and began working as an independent productivity consultant, using the TOC approach.  This culminated in his founding the TOC Centre of Australia (TOCCA) in January 2000. 

With David at the helm, TOCCA has developed a diverse Australian clients list, including the likes of BHP Billiton, Cadbury Schweppes, Smorgon, CSC, Rail Infrastructure Corporation, Sunbeam, Sensis, Orrcon and many more.

David's working history also includes:

·               Consulting work to the IT divisions of Wesbank and First National Bank, two of South Africa’s largest commercial banks, as well as the National Productivity Institute and a number of smaller companies

·               Pioneer adopter of Critical Chain methodology in South Africa 

·               Managing Director of Matador Refrigeration, a large Commercial Refrigeration Company

·               Managing Director of Gerber Goldschmidt Distribution, a large distribution business in Johannesburg, South Africa 


David is a highly accomplished presenter and facilitator, and receives consistently high ratings from attendees at his presentations and workshops.
