By ratcheting the process towards this aim with focused muda reduction to achieve each step, the improvements are 'locked in' and become required for the process to function.

The primary steps he lists in tackling waste are: These simple steps rely on awareness, discussion, and accountability as much as they rely on analysis or action. This is primarily where … You can read more about these efforts in our post on process implementation. The most obvious forms of wasted movement involve poorly organized factories or service assemblies where workers need to walk around the space to gather equipment or tools to complete their tasks. Muda translates roughly as waste, and refers to the inefficiencies within processes which you can seek to reduce or eliminate entirely. For a really simple overview of the basics of how Process Street works, check out this 1 minute video below! Domingo compares hidden wastes to an iceberg; once you spot the tip you should know that there’s a greater body hidden under the surface.
