The 7 Wastes
I’m sure you have heard of the 7 wastes of manufacturing.
An easy way to remember these is to use the acronym “WORMPIT”. There are a couple of different terminologies in use by different practioners, however they all cover the same wastes.
Of all of these wastes, overproduction is the greatest waste. Overproduction contributes to all other wastes. With overproduction, you will also find Inventory, Transportation, Walking, Rework, Motion, and often overprocessing.
Remember, a waste is any action that the customer is not willing to pay for.
