Wasted human talent – Damage to people
Defects – "Stuff" that’s not right & needs fixing
Inventory - "Stuff" waiting to be worked
Overproduction – "Stuff" too much/too early
Waiting Time – People waiting for "Stuff" to arrive
Motion – Unnecessary human movement
Transportation – Moving people & "Stuff"
