Warehouse metrics
How much of the pick facesits within easy reach.
Golden-zone share is the proportion of picks that come from the height band where reaching and stooping are minimised — waist to chest, roughly, for most people — weighted by how often each SKU is actually picked, not by how many SKUs happen to sit there. It's an exposure measure, not a prediction: it shows how much of today's picking volume sits at a safe height and how much doesn't, so a slotting decision that quietly moved a fast mover out of easy reach shows up before it's been sitting there for months.

What it is
Weighted by the pick, not just the slot.
On WareBee's digital twin, golden-zone share is the proportion of picks that happen from a location inside the golden zone — the waist-to-chest height band where reaching and stooping are minimised for most people — weighted by how often each SKU is actually picked, not by how many SKUs are simply assigned there. Every location carries that band, and a SKU's placement inside it tracks live pick frequency rather than a slot chosen once at go-live and left alone, so the share reflects where picking volume is actually happening today.
The share moves with how closely slotting tracks live demand rather than the catalogue as it stood when the racking went in. A SKU that spikes for a season and stays in the location it was assigned before the spike quietly drops out of the golden zone the moment its pick frequency outpaces its height band. A catalogue that keeps growing without the golden zone growing to match ends up with more fast movers competing for the same limited height than the layout was ever built to hold. And a reslotting cadence that runs rarely lets that drift accumulate for a long stretch between the corrections that would otherwise catch it early.
How large a golden zone even is differs before any slotting decision gets made — a warehouse holding a handful of fast movers in a tight footprint can keep nearly all of them inside that band, while one running a sprawling catalogue across a much larger footprint is competing for the same limited height across far more items. WareBee reads your share against a peer set matched on order profile, SKU count and footprint, so a figure that looks thin against a narrow catalogue means something different once it's set beside operations actually carrying a comparable range.
What moves this number
What quietly moves a SKU out of easy reach.
Each one is measured on your digital twin from data you already generate, so a golden-zone gap traces back to a specific SKU and cause rather than a general sense that the pick face feels harder than it should.
Demand drifting faster than the slot
A SKU's pick frequency climbs or falls and the location it's assigned to doesn't move with it, so the golden zone stops matching where picking is actually happening.
Each location's height band is checked against live pick frequency rather than a slot chosen once and left, so a SKU drifting out of its frequency band is visible before it's been sitting there for a long stretch. A fast mover left in place after a season ends is exactly the kind of drift the reading catches.
A catalogue that outgrows the height it's competing for
The golden zone is a fixed amount of shelf; a catalogue that keeps adding fast movers eventually has more of them than that height band can hold.
Golden-zone share tracks how many of a growing set of fast movers are actually winning a place in that band versus being pushed to a less reachable height as the catalogue expands. Nothing about the band itself gets bigger just because more SKUs need it.
Weight and handling class assigned after the fact
A location gets picked for velocity first, and what the item actually weighs to lift only gets checked once it's already sitting there.
Mass and handling class are checked against a location's height band before a slot is confirmed, not discovered after the fact, so a heavy case doesn't get placed somewhere awkward to reach purely because that's where the fastest slot happened to be free.
Reslotting that runs on a calendar, not on drift
A yearly reslotting cycle catches a golden-zone drift only once a year, no matter how early in that year the drift actually started.
Because placement is checked continuously against live pick frequency rather than at a fixed calendar interval, a SKU that's drifted out of the golden zone shows up as soon as the drift happens, not whenever the next scheduled reslot happens to fall.
Where the golden zone is thin, and which SKUs are missing it.
A single golden-zone-share figure for the warehouse doesn't say which SKUs are actually outside the band, or why. Once yours is read against a peer set matched on order profile, SKU count and footprint, the next question is whether the gap is coming from demand that's drifted since the last reslot, a catalogue that's outgrown the height available, or handling-weight rules that were never checked before a slot was confirmed — the same placement and pick-frequency data that builds the figure breaks it down by SKU.
Re-slotting for golden-zone share is simulated against real orders before anything moves, so the travel and throughput trade-off — moving a fast mover up a shelf can add a step to a different route — shows up on screen first, not after a pallet's already been relocated. Once a plan is approved, it reaches the WMS as the moves and location assignments it already understands.

Questions
Golden-zone share, read the right way.
What exactly counts as the golden zone?
It's the height band on a rack — roughly waist to chest for most people — where reaching and stooping are minimised. Golden-zone share is the proportion of picks, not SKUs, that come from a location inside that band, weighted by how often each item is actually picked, so a handful of fast movers sitting outside it counts for more than a long tail of slow movers sitting inside it.
Does a higher golden-zone share mean fewer injuries?
No, and WareBee doesn't claim that. It measures exposure — how much of your picking volume happens at a safe height today — not the likelihood of an injury, and it isn't a substitute for a proper ergonomic assessment or a health-and-safety professional's judgement. What it does is show where the pick face is asking for more reaching or stooping than it needs to, which is a fact you can act on regardless of what any single number predicts.
Why does golden-zone share change even if nobody re-slots anything?
Because it's weighted by live pick frequency, not by a fixed slot list. A SKU can sit in exactly the same location for months and still move the share, purely because how often it's picked has changed — a seasonal item spiking in demand while parked outside the band pulls the share down without a single location assignment being touched.
Is there a fixed golden-zone share every warehouse should be hitting?
Because a golden-zone share on its own can't say whether it's low by design or low by neglect — a peer set can. WareBee checks order profile, SKU count and footprint first, then reads your share only against operations assigned a genuinely similar range of fast movers to the same limited height, so what counts as thin gets decided by a fair comparison, not a number picked without knowing what your pick face was ever asking of it.
What data builds a golden-zone share reading?
Location and item master data, stock positions and pick history are enough for a first read — the exports most WMS platforms already produce. Wearable and scan data sharpen the picture of bend, reach and carry per associate further if you already have them, but nothing about the core golden-zone reading waits on new hardware to get started.
Does a re-slotting move for golden-zone share reach the WMS?
Yes. Once a re-slotting plan is approved, it exports as the location moves your WMS already imports, so the change proven to lift golden-zone share on the twin is the one that actually happens on the floor. Pick data updates continuously afterwards, so the next reading is built from where items genuinely ended up, not from what the plan intended.
