McDonald’s in France has over 1,500 restaurants and 70,000 employees. The French market is recognized as the most difficult market in the world because clients eat at very specific times and the culinary expectations are very high. It has for many years been one of the most innovative of McDonald’s markets.
When rolling out the new “Made For You” global operational model they took the opportunity to rethink how they managed operations in their restaurants. 
Using a mixture of Theory Of Constraints, Lean and common sense McDonald's redefined how they managed flow.
As a result client service times were significantly reduced and global efficiency increased.


Aerosud is a fully and explicitly Theory Of Constraints company from operational flow management on the shop floor to its strategy described in the form of a Goal Tree.
The company, based in South Africa, produces aeronautical equipment for Boeing, Airbus and other key actors. Their TOC journey started in 2010. It first applied TOC to its Supply Chain and Manufacturing with great success. It later implemented Critical Chain Project Management to its new product development and broke the world record in performance finishing 98% of its projects on time.
Then in March 2020 the Covid-19 pandemic struck them and the aeronautical industry. Their response was to trigger and co-lead a South African initiative to rapidly develop the products that the country needed to face the crisis. Today Aerosud has repositioned themselves to continue to thrive in the new context.

EuroCryospace (Ariane rockets)

EuroCryospace is a subsidiary of Air Liquide and Ariane Group. The company manufactures the main “stage one” cryogenic tank for the Ariane 5 rockets. Facing difficulties to meet the customer's need and changes in external & internal context of the aerospace activity, the situation prompted the facility to implement the Theory of Constraints in order to increase the production rates.
Significant results were quickly obtained:
• The rocket production rate increased by 25% with no investments whilst simultaneously switching from a 3 shift to 2 shift organisation.
• The waiting time at quality control reception was reduced by 85%,
• The output of the bottleneck of the first stage sections production increased by 60%.
