Muri, overload in LeanNo + 無理
The name says it all. Muri is one of the three fundamental wastes in Lean: overload. “No muri” is the commitment to bring it down to zero.
The vocabulary of Lean
Muda, mura, muri
The Toyota Production System distinguishes three families of waste. Most companies chase the first. nomuri focuses on the third, the most human. Every term is in the Lean glossary.
Muda
wasteAny activity that uses resources without creating value.
Mura
unevennessJolts, peaks and troughs that wear down systems and people alike.
Muri
overloadAsking a person or a machine for more than they can reasonably give.
Why now
The cost of overload is soaring.
Burnout has become a financial, organisational and human burden, and a particularly heavy one in healthcare. Absenteeism, staff turnover, recruitment difficulties and falling quality: repair always costs more than prevention. nomuri addresses the cause, overload, rather than its consequences.
The guiding principle
Respecting people means giving them intelligent work.
Genuine Lean is not about making people run faster. It clears away whatever stops them from doing their job well. nomuri automates thankless tasks, informs decisions and gives teams time to think.
From philosophy to software
Three principles in every product.
Anticipate
Make overload visible before it strikes: diagnosis, early signals, projection.
Decide
Offer clear, ranked options that follow the rules. The software informs, people decide.
Respect
Protect people: private data, a manageable workload and meaningful work.
FAQ
Frequently asked questions
What does muri mean?
Muri (無理) means “unreasonable” in Japanese. In Lean, it means overload: asking a person or a machine for more than they can reasonably give.
What is the difference between muda, mura and muri?
Muda is waste, mura is unevenness and muri is overload. They are linked: unevenness creates peaks of overload, which in turn produce waste.
How do you reduce overload at work?
Make it visible (workload against capacity, for example with a yamazumi chart), level the demand (heijunka) and rebalance the tasks.
Where does the name nomuri come from?
From “no muri”: zero overload. The name is every product’s commitment.
