Reading a pick face without staring at a screen
Fast movers tell you more from scuffed floor tape and empty slots than from a location report printed the night before.
Pick faces age in public. The tape that once marked a golden zone peels. A slot that should hold a case of cooking oil sits empty while the same line is overstocked two bays down because last week’s delivery was dumped where the truck could reach. A location report from Tuesday night will not mention either fact by Thursday lunch.
On observation days we walk the same route a picker takes for a typical wholesale order: dry grocery, then chilled, then bulky. We count the extra steps caused by a blocked aisle, a pallet left in the travel lane, and a slot that has drifted from its label. The conversation with the picker matters more than the count. They will tell you which lines they ‘just know’ are in the wrong place, and which they still hunt for because the label was never reprinted after a reset.
Charts from this walk are deliberately dull: a plan of the aisle, arrows for travel, and a handful of call-outs in plain language. Warehouse managers sometimes want heat maps. Heat maps look decisive and hide the blocked pallet. The dull plan does not.
Bring a typical order sheet, not a perfect one. The messy order is the one that shows where your pick face actually lives.
