We don't adapt Lean from a textbook. Fourtre practitioners were trained at the source — building a living Toyota Production System on your floor.
Most plants are sitting on 20–40% of hidden capacity — buried in overproduction, waiting, and firefighting. We make it visible, then build the operating system that keeps it flowing without new capital.
Every engagement is run by practitioners trained through Toyota's OMDD and TSSC. We start where you are and build a system that lasts after we leave.
A rapid, gemba-based read on where your hidden capacity lives — and what recovering it is worth.
Prove flow on one line using the TSSC methodology, then scale the operating system across the plant.
Build the Team and Group Leader capability that makes improvement self-sustaining long after we're gone.
Authentic Toyota Production System isn't just for the assembly line. We've proven it across four very different operating environments.
Assembly, fabrication, and machining — high-mix, complex BOMs, and the flow challenges that come with them.
Office and service flows — order-to-cash, claims, and back-office processes. Yes, TPS works off the shop floor.
New lines and plants designed right the first time with 3P — before capital is committed to the wrong layout.
Continuous and batch operations — food, chemicals, and materials, where changeover and OEE drive the gains.
Selective engagement, measurable outcomes. A sample of what recovering hidden capacity looks like.
What we're learning deploying authentic TPS — the thinking, the proof, and the deeper research.
Kaizen events deliver a step-change, then the gains quietly erode. The fix isn't another event — it's the management system that turns a sawtooth into a staircase.
