Line-side replenishment is visual chaos
You run out of packaging or ingredients at the line and lose production hours while someone hunts for materials.

The problem
Who feels it most
Operators waiting for materials, warehouse runners, and supervisors managing ad-hoc replenishment requests.
How common is this?
Inventory accuracy at the line-side level is an ongoing challenge. Line-side processes amplify discrepancies between system records and physical reality.
Typical workaround today
A 'runner system' with verbal requests, shout-based kanban, physical kanban cards, and Excel tracking that's always outdated.
Why ERP / WMS doesn't solve it
WMS sees warehouse locations but not consumption timing at the line. ERP MRP is too slow for hour-by-hour replenishment needs.
Business impact
'Starved line' downtime minutes — often the largest single downtime category
Overtime and expediting from delayed replenishment
Invisible cost: the correlation between replenishment latency and downtime is never measured
Digital kanban with min/max levels and replenishment task tracking
Define line-side kanban bins per item with min/max levels and replenishment source locations.
Operator taps 'bin empty' on the tablet (or scans a bin QR code) — a replenishment task is created instantly for the warehouse team.
Warehouse team sees pending replenishment requests with priority and location, fulfils them, and marks complete.
Response time tracking links starvation downtime to replenishment latency — making the cost of slow replenishment visible.
Start with the top 20 packaging items and expand — no need to model the entire warehouse from day one.
