Lean 5S for Stockrooms: Discipline That Shows Up in Counts
Sort, set, shine, standardise, sustain — the warehouse hygiene that makes expiry, damage, and mis-picks visible early.
A branch manager found dated stock tucked behind a fast-moving SKU last Tuesday — the write-off hit before anyone had time to argue about whose count was right. 5S (sort, set in order, shine, standardise, sustain) keeps stockrooms safe, fast, and auditable — a foundation for accuracy, not a poster campaign. It supports slotting, count quality, and fewer “I think it is behind that pallet” moments.
Key terms in this guide: Safety stock, Cycle counting, Perpetual inventory.
