Why cycle counts fail on busy Taiwan plant floors
Missed locations, borrowed counters, and WIP that never stops moving—how manufacturing rhythm undermines inventory counts.
Cycle counts look tidy on a calendar and messy on a Tuesday afternoon when three rush orders pull the same SKU from two aisles. In many Taiwan manufacturing SMEs, the count sheet is finished, yet the variance still lands in the month-end suspense account.
Counters who also ship
When the same warehouse lead both picks and counts, small shortages get “explained” before they reach finance. A controls review looks for independent count teams—or at least a second signature that is more than a courtesy stamp.
Locations that exist only on the map
Open cartons on the line, quarantine cages, and tooling rooms often sit outside the cycle-count route. Scrap bins are worse: material leaves inventory in the system days after it left the rack.
WIP that never freezes
Partial assemblies move between stations while the count is underway. Without a short freeze window or tagged WIP baskets, quantity and stage both drift. Reviewers ask how stage is evidenced—not only how many pieces sit on a bench.
What plants fix first
The strongest early fixes are usually route completeness, independent observation of high-value SKUs, and a same-day posting rule for scrap. Software upgrades help later; discipline on the floor helps now.
