Clients & Cases

Results you can verify.

Theory of Constraints is not a slide deck — it is inventory that dropped, lead times that halved, and satellites that launched. These are implementations we ran, at companies you can call.

–40% Inventory through Brabantia's global supply chain — at very high service levels.
–50% Production lead time at TKF, worldwide — tangible within 8 months.
Orbit The Proba satellite, delivered in 3 years with Critical Chain at Verhaert Space.
The proof

Six implementations, six domains

Supply Chain · Dynamic Replenishment

Brabantia — household products, 80 countries

Multiple C&DS modules across 5 plants and 3 distribution centres: consumption-driven replenishment for finished and raw materials, buffer management for shop-floor priorities, and POOGI. Result: very high service levels with –40% inventory through the global supply chain — and a planned new UK warehouse cancelled, the existing one running at half capacity.

Production · Internal Supply Chain

TKF — cable manufacturing, worldwide

C&DS production planning (MTO/MTS with available-to-promise), Buffer Management and Dynamic Replenishment across three plants, integrated with their ERP over a 12-month implementation. Result: –50% lead time and –30% finished-goods inventory, with tangible results inside 8 months.

Projects · Critical Chain

Verhaert Space — the Proba satellite

The first Belgian satellite, and ESA's first fully autonomous spacecraft — built in 3 years at a fraction of the conventional budget, with five earth-observation instruments on board. Critical Chain brought more stable planning, clear priorities and better risk management. Proba launched and exceeded expectations.

Projects · Multi-Project

Baxter — healthcare, Europe-wide projects

Critical Chain for large European projects, starting with the VIALFLO technology conversion — technical and marketing work synchronized across teams. The project was delivered before its planned due date, and Baxter continues to use Critical Chain for most of its European projects.

Production · Buffer Management

Deknudt Mirrors — premium mirror manufacturer

A Belgian family firm crafting premium mirrors since 1946. C&DS Buffer Management brought the right focus to the shop floor and the purchasing department — from design to a live shop floor in 6 months.

Purchasing · Material Availability

Engie Electrabel — nuclear plants Doel & Tihange

The purchase department faced a growing volume of complex, urgent requests with a shortage of skilled people. TOC-based material management (interfaced with SAP) brought stock optimization, kanban-style priority steering and obsolescence alerts. Result: flows under control without additional recruitment — technicians find their information without waiting on other services.

And many more

Trusted across industries

Beyond the six cases above, we've worked with manufacturers, energy companies and service providers across Europe.

The pattern

What every implementation shares

Different industries, different constraints — the same disciplined route from diagnosis to results that stick.

1 · Scan

A short diagnosis

Where does flow break, where is the real constraint, how much potential is on the table? Weeks, not months — and it ends in a number.

2 · Plan

A clear decision document

What changes, what it delivers, what it asks of your organisation. You decide on evidence, not on a promise.

3 · Implementation

Results in months

Together with your team, step by step — TKF saw tangible results in 8 months, Deknudt Mirrors went live in 6. Know-how transfer included, so the results outlive the consultants.
