Measure too little and you fly blind. Measure too much and you bury the signal in noise. Here's a short list that won't lie to you.
The 12 that matter
- Inventory accuracy (% SKUs with zero variance).
- On-time dispatch rate.
- Order accuracy rate (% orders with zero errors).
- Pick rate (units per picker hour).
- Receiving cycle time.
- Put-away accuracy.
- Carrying cost as % of inventory value.
- Dead stock as % of inventory value.
- Backorder rate.
- Average days on hand.
- Return rate by SKU.
- Cost per order shipped.
The 5 to ignore
- "Warehouse utilisation %" � counts space, not value.
- Number of POs raised � a vanity metric.
- Stock turn for the whole warehouse � only meaningful per SKU class.
- Average order size � useful only if linked to margin.
- Number of suppliers � more is not better.
