Muda (無駄; on'yomi reading, ateji) is a Japanese word meaning "futility", "uselessness", or "wastefulness", [1] and is a key concept in lean process thinking such as in the Toyota Production System (TPS), denoting one of three types of deviation from optimal allocation of resources.
That’s where the concept of Muda comes into play. In Lean Six Sigma, Muda is the Japanese term for waste – or any activity that consumes resources without adding value from the customer’s perspective. This waste slows operations, inflates costs, and doesn’t improve the product or service.
Muda means wastefulness, uselessness and futility, which is contradicting value-addition. Value-added work is a process that adds value to the product or service that the customer is willing to pay for. There are two types of Muda, Type 1 and Type 2.
In Japanese, "muda" means uselessness, futility. Together with mura and muri, muda serves to identify the non-value-adding, wasteful activities within a process. Learn what kinds of muda there are, how to identify them and what to do to minimize them for a more efficient process.
The original seven forms of waste (muda) were identified by Taiichi Ohno, the engineer behind the Toyota Production System (TPS). These seven mudas include overproduction, waiting, transportation, overprocessing, excessive inventory, unnecessary movement, and defect production.
