We possess the real, hands-on experience that you have been looking for, for so long. With over 20 years of leading JIT systems development and deployment experience, you can rest assured that our services are as relevant and practical as they can be.


“There is nothing is more practical than a good theory”. Our services are practical and hands-on, but also strongly rooted in a thorough understanding of the underlying theories. To make sure we don’t just drop the tools, but we adapt them to your context based upon the underlying principles.


Our services are packed with examples, games, videos, pictures, discussions, and simulations. They are delivered in a highly interactive way by experienced leaders, full of anecdotes, and passionate about just-in-time manufacturing.

We partner with manufacturing and logistics companies across the globe, to help them deliver their customers on-time and in-full, at the lowest possible cost, and with a minimum of inventory.

With over 20 years of hands-on experience in leading just-in-time systems development and deployment across international manufacturing sites, THE JIT COMPANY is very well-positioned to support you on your journey towards excellence.

Our mission is to help you create and sustain flow in your supply chain, so you can deliver your customers on-time and in full, at the lowest possible cost, and with a minimum of inventory.

Learn how to make only what is needed, when it is needed and only in the amount needed, using kanban, one-piece flow and heijunka. The three core principles that make up the just-in-time philosophy.

We provide blended e-learning and classroom training, learning materials and academy services, assessments and dynamic simulations, and on-job implementation support and materials to help you transform your supply chain into a lean, just-in-time value stream.

THE JIT COMPANY was founded in 2019, by Dumontis — a Lean consulting and coaching company that has been around since 2011. We are rich in practical experience, rooted in theory, engaging and inspiring.

Rich in practical experience.

Practical relevance is often seen as the most important aspect of the type of services we provide. And with our 20 years of hands-on experience, you can rest assured, that what you will get is relevant, practical, and applicable.

And we have seen a lot! From basic two-bin applications on bolts and nuts, through challenging heijunka applications for a configure-to-order equipment manufacturer, up to complex production wheels in the process industry, working in pull flow.

Rooted in relevant theory.

Creating and sustaining flow requires a thorough understanding of the factors that inhibit flow. If you like it or not, there are proven theories behind the concept of flow that can explain what is happening in your value stream. And that can help you develop a strategy to counter those negative effects.

The practical tools you witness in world-class companies are all based upon a deep comprehension of those theories. Neglecting them results in just applying a tool, instead of adapting it to your context based upon the underlying principle.

Engaging and inspiring.

Change requires more than just theory and practical tools. It requires leadership, engagement, and inspiration. We breath just-in-time. It is our passion.

With over 20 years of experience in developing and deploying just-in-time initiatives across international, multi-site organizations, THE JIT COMPANY is very much aware of the challenges on the road to excellence.

Part and parcel of what we do, therefore, is developing this same passion in the people we work with.
