Reading Dwell Time at Thai Regional Depots

Dwell time is the quiet metric that explains why evening cutoffs slip even when the yard looks busy. At southern Thai depots we visit, cartons often clear receiving quickly, then sit in a staging lane waiting for a pick wave that never quite matches the outbound appointment board.

Start with three timestamps if your WMS or paper log can supply them: put-away complete, pick release, and dock-door assignment. The gap between the first and second usually reveals replenishment lag; the gap between the second and third shows dock congestion or missing carrier slots.

On island feeder routes out of Phuket, dwell stretches further when refrigerated lines share lanes with ambient freight. Supervisors who only watch on-time departure percentages miss the hours those chilled crates spent warming in mixed staging.

A practical weekly habit: sample twenty SKUs across fast and slow movers, chart their median dwell, and walk the lane where the longest waits accumulate. Charts alone rarely persuade a shift lead—standing in the aisle with the numbers usually does.
