Combining the Theory of Constraints and Lean to go further in performance improvement, by Philip Marris
Two high-performing methodologies, the Theory of Constraints (TOC) and Lean, have proven their worth individually. But what happens when you combine their strengths to achieve even better results?
Join Philip's conference to clarify the foundations of TOC and Lean, and discover how they complement each other.
The Theory of Constraints helps identify bottlenecks, meaning it helps pinpoint the resources to focus on and apply Lean's waste reduction techniques.
Through concrete examples, discover how organizations have successfully combined the two approaches to streamline their operations and increase efficiency.
Participate and leave with tips for gaining team buy-in and ensuring the sustainability of the results achieved.
Philip Marris a commencé son parcours en 1986 quand il a rejoint Creative Output et collaboré avec Eliyahu Goldratt, inventeur de la Théorie des Contraintes et auteur du bestseller mondial "Le But". En 1994, Philip écrit à son tour un livre sur la TOC, en français, pour expliquer comment mettre en application les idées du roman "Le But".
