Notes on warehouse flow.

Practical writing on layout, slotting and picking efficiency from the people building WalkBill.

23 Jun 2026 From one CAD drawing to a working warehouse twin You do not need a WMS or a perfect dataset to model your warehouse. Here is what a single layout drawing, a location list and pick history actually get you.
23 Jun 2026 Warehouse simulation without a simulation engineer Between free box-drawing tools and six-figure simulation platforms there is a gap. Here is what a lightweight, self-serve 3D warehouse model can and cannot do.
23 Jun 2026 Golden-zone slotting: which SKUs belong at the front The golden zone is your cheapest pick-efficiency lever. Here is how to decide which SKUs earn a place at the front, and the mistakes that waste it.
23 Jun 2026 The spaghetti diagram that moves: warehouse flow in 3D The hand-drawn spaghetti diagram is a brilliant Lean tool, but it is static and ages instantly. Here is the case for one that animates as a day runs.
23 Jun 2026 Pallet positions vs walking distance: the missing number Racking proposals are scored on capacity. Almost nobody scores the walking the layout forces. Both axes matter, and they can disagree.
13 Jun 2026 What a wasted pick-walk actually costs you Pickers spend most of a shift walking, not picking. Here's how to turn that travel into a pound figure you can act on.
12 Jun 2026 Re-slot before you re-rack: the cheapest warehouse win New racking is capital. Moving your fastest movers closer to dispatch is free, and often captures most of the gain.
11 Jun 2026 You don't need a WMS to map your warehouse flow Plenty of sites run on paper and spreadsheets. You can still map how your warehouse moves, and put a price on it.
