8 Wastes

Defects, Inventory, Processing, Waiting, Motion, Transportation, Overproduction, and Non-Utilized Talent. These eight wastes are common steps within any operation which add no value to the customer. The original 7 Wastes were described by Taiichi Ohno, and have since been added on to as Lean moves into industries that deal with more than simply physical production.
