Muda (ç¡é§) is a Japanese word meaning futility; uselessness; idleness; superfluity; waste; wastage; wastefulness, and is a key concept in the Toyota Production System (TPS) as one of the three types of deviation from optimal allocation of resources (muda, mura, muri).uda has been given much greater attention as waste than the other two which means that whilst many Lean practitioners have learned to see muda they fail to see in the same prominence the variation of mura (unevenness) and muri (overburden).
