What are the wastes in logistics?
The eight wastes of lean show up in a warehouse or transport network in familiar forms:
| Waste | What it looks like in logistics |
|---|---|
| Transport | Double handling between docks, racks and trucks |
| Inventory | Overstock, slow movers, safety stock nobody owns |
| Motion | Pickers walking long routes or searching for stock |
| Waiting | Trucks queuing at the dock, orders waiting for a pick |
| Overproduction | Picking or shipping ahead of the order |
| Over-processing | Repeated checks, re-labelling, duplicate paperwork |
| Defects | Mis-picks, damaged goods, wrong deliveries |
| Unused talent | Ideas from drivers and pickers never captured |
How do you make logistics lean?
- Map the flow. A value stream map from supplier to customer shows where goods wait and how long each step takes.
- Pull, don't push. Replenish from actual consumption using kanban bins or cards, as in lean stock.
- Level and pace the flow. Use takt time and smaller, more frequent deliveries instead of large irregular batches.
- Organise the space. 5S, marked locations and first-in-first-out lanes cut search and travel time.
- Write the standard. Document the best-known way to receive, pick, pack and load as standard work.
- Review daily and improve. Short huddles on late orders, mis-picks and damage feed small kaizen fixes.
Lean logistics vs supply chain management
Supply chain management covers sourcing, planning, contracts and relationships across the whole network. Lean logistics is narrower and more hands-on: the physical flow of goods and the information that triggers it, judged by how much waste each step contains.
Example
A distribution centre found that pickers walked far to reach fast-moving lines and that outbound trucks waited for loads staged too late. The team moved fast movers next to the packing area, set a pick-and-stage cut-off for each departure time and posted late and wrong-item counts on a board reviewed at the start of every shift. Mis-picks and dock waiting became visible, so causes were fixed within days rather than discussed at month end.
