Examples of Waste
| Waste | Example | Implication |
| Defective Products
|
parts incorrect from supplier
incomplete information |

additional costs built-in
obsolescence, count, store |
| Excessive Inventories | inventory investment ‘sleeping’
6mo. of paper at every copier |
long lead-time, rework, lost
high cost, never right size |
| Excessive Motion | 30% time looking for parts, tools
paper not next to copier |
barriers to adding value
ergonomics, safety |
| Excessive Processing | hand finish
functional signatures |
ineffective use of skills
no decision rules, travel dist. |
| Transportation | bad layout
process monuments |
invest to cover inefficiency
batch processing, no flow |
| Waiting | investment sits for next ‘event’
batching, signature cycles |
