I learned about the concept of Muri at Toyota.
I was surprised to find that many Lean practitioners either never use it or barely pay it lip service. It is one of the most crucial lead productivity measures of all.
Muri means overburden
Muri is a Japanese word used in The Toyota Way. It means the unnecessary and unreasonable struggle in a system. Just as materials should flow seamlessly with minimum fuss and effort, the same should be true for people.
