Lean Six Sigma refers to the eight types of waste it strives to eliminate as "DOWNTIME," which is an abbreviation of "Defects, Overproduction, Waiting, Non-utilized talent, Transportation, Inventory, Motion, and Extra-processing." Simply put, any use of resources that doesn't create value for the end customer is considered a waste and should be eliminated
