The 8 Lean wastes - "TOM D WIPS"
Inefficient transportation; unnecessary movement of parts / files / equipment without creating value
Example technique : reduce inventory, approvals
2. Over Production
Production more than required or before time causes waste
Example technique : Kanban (signal to produce upstream)
Unnecessary human movement. Walking to & from copier , bending down to pour water, too many clicks on a site
Example technique : 5S, human-centric design
Waiting for previous step to complete work, so that you can do your work
