How many types of waste were defined by Toyota?

Waste does not add any value to a product or service. Toyota engineer Taiichi Ohno came up with seven categories of waste (called muda in Japanese): waiting, transporting, processing, inventory, motion, defects/rework, and overproduction.

What are the seven important sources of waste according to Toyota?

Taiichi Ohno and Shigeo Shingo, the two cofounders of the Toyota Production System, identified seven possible sources of waste: transportation, inventory, motion, waiting, overprocessing, overproduction, and defects. (A nice mnemonic to remember these seven sources is TIM WOOD.)

It just so happens that there is one bundle of tricks known as the “5 S’s.” Pediatrician Harvey Karp pioneered this method when he brought together five techniques that mothers have often used and organized them into this easy mnemonic: swaddle, side-stomach position, shush, swing, and suck.

What are the seven wastes of lean manufacturing?

Under the lean manufacturing system, seven wastes are identified: overproduction, inventory, motion, defects, over-processing, waiting, and transport. The most serious of the wastes, overproduction can cause all other types of wastes and results in excess inventory.

What are two types of waste at play?

Here, we see at least two types of waste at play: Waiting and Overproduction. Even more, how the desire to not stay idle, leads to motion, overproduction, and ultimately leading to more inventory than was needed. At the end of this chain, we find that there were 5 types of waste at play – each feeding the other.
