Muri is one of three types of waste (muda, mura, muri) identified in the Toyota Production System. Waste reduction is an effective way to increase profitability. Muri can be avoided through standardized work. To achieve this a standard condition or output must be defined to assure effective judgment of quality. Then every process and function ...
From an end-customer's point of view, value-added work is any activity that produces goods or provides a service for which a customer is willing to pay; muda is any constraint or impediment that causes waste to occur. [3] There are two types of muda: [4] Muda type I: non value-adding, but necessary for end-customers. These are usually harder to ...

It is also crucial to ensure that the process is as flexible as necessary without stress or "muri" (overburden) since this generates "muda" (waste).

While lean manufacturing focuses on optimization of the production stream and removal of wastes (commonly referred to as muda, mura, and muri) once the value stream has been created, Lean Design ® (Munro & Associates) concerns itself with methods and techniques to create a lean solution from the start, resulting in more value and fewer wastes ...
Lean thinking's approach, seeking to eliminate waste in the form of muri (overburden), mura (unlevelness) and muda (unnecessary resource use), is a proven practical way to attack complex problems piece by piece through concrete action.
