START WITH THE RIGHT PROBLEM
Not every visible problem is the real problem.
An organisation may see many symptoms. We help identify the constraint that limits the entire system — and focus the team’s energy where it can create the greatest impact.
Performance & Flow
Performance stalls even though the number of initiatives keeps growing.
Priorities compete with each other, processes fail to flow, and teams optimise their own parts of the system.
Machines & Maintenance
Breakdowns dictate the pace of work.
Maintenance teams keep firefighting, OEE declines, and the root causes of losses remain outside a shared improvement system.
Quality & Standards
Quality depends on who is doing the job.
Knowledge remains in experts’ heads, standards are not truly embedded, and the same problems reappear elsewhere in the process.
People & Capabilities
New employees take too long to become independent.
Onboarding does not scale, instructors teach differently, and leaders lack the time to develop their people.
Leadership & Change
Strategy does not translate into everyday work.
Leaders react instead of leading change, goals remain disconnected from the Gemba, and improvement loses momentum once the project ends.
We do not start with a training catalogue. We start with one question: what is currently limiting your organisation’s ability to achieve results?
OUR TRANSFORMATION SYSTEM
LeanTrix Transformation Loop.
Not another set of tools, but a system for leading change. We combine strategic direction, constraint identification, experimentation and capability building into one repeatable improvement cycle.

The outcome is not only an improved process. The organisation learns how to independently identify the next constraints and lead further cycles of improvement.
FROM INSPIRATION TO TRANSFORMATION
Start where you are ready today.
Some organisations first meet us at Lean Summit, others during a workshop inside a factory or through a conversation about a specific business challenge. Every path can lead to sustainable change.

Lean Summit
A meeting of practitioners, leaders and organisations that are changing the way work gets done.
Experience
Open Workshop
Hands-on practice in a real process environment — at Toyota, PepsiCo and other organisations.

CLIENT REFERENCES
Case Studies show the results. References show the trust behind them.
We publish references available in their original form: signed client documents and public recommendations from participants in our programmes.
TRUSTED BY
We work with companies that want real change.
From manufacturing and logistics to services and healthcare. We support organizations that want to improve performance, develop people, and build sustainable ways of working.
CAPABILITIES WE BUILD
We do not sell a methodology. We build the capability to deliver results.
Lean, TWI, TOC, Toyota Kata and quality tools are selected according to the constraint. The starting point is always the business outcome and the team’s ability to achieve it.

Start by identifying the right problem.
A free consultation is about understanding the situation — not presenting a ready-made offer. If we see an opportunity to work together, we propose a diagnosis. Only then do we define the scope of the project.

FAQ
Have questions? Start here.
Below we answer the most common questions about our work, cooperation and project delivery. Briefly, clearly and without unnecessary formalities.
What does LeanTrix do?
We build organisational capabilities across processes, people, quality and management. We implement Lean, TWI and Theory of Constraints in manufacturing, services, logistics and construction.
We do not stop at training — we leave behind a standard and measurable results.
We organise one of Europe’s largest conferences dedicated to Lean Management — Lean Summit.
We also run open workshops inside leading companies in Poland, including Toyota.
Do you work only with Lean and TWI?
No. Lean and TWI are the foundation, but our projects also involve TOC, quality management, change management, onboarding, frontline leadership and digital tools such as eTWI and KaizenUp.
Who is it for?
For manufacturing and service organisations that have reached a certain scale and struggle with repeatability: onboarding takes too long, bottlenecks stop the flow, quality fluctuates or leaders spend their time firefighting. We work both with mid-sized plants and large corporations.
What is the difference between implementation and training?
Training provides knowledge. Implementation changes how work is performed on the shop floor or within the process — including the standard, instruction, leadership routines and performance indicators. That is why we show Case Studies, not just course programmes.
How long does a typical project take?
A pilot and the first standards usually take several weeks to three months. A broader transformation within an area typically takes 6–12 months. The average payback period of our implementation and training projects is approximately seven months.
Where can I see the results?
In more than 30 publicly available implementation Case Studies, including VELUX, Danone, Bosch, Autoliv, eObuwie and Tarczyński.
Is it only for manufacturing?
No. Manufacturing and automotive are important areas for us, but we also work with logistics, e-commerce, healthcare, construction and service organisations. We also cooperate with the International Lean Six Sigma Institute, making internationally recognised certification available.
How do we get started?
Start with a 15-minute consultation. Tell us where the process or employee onboarding is causing problems. We will tell you whether the challenge is best addressed through TWI, Lean, TOC or quality — and whether a project makes sense at all.
Is funding available?
Some programmes are available through the BUR funding system. During the consultation, we can determine whether a particular programme may qualify. We do not promise funding in advance.
