Separate missing stock from missing information
When an order cannot be supplied, first check whether the item is physically absent, in another location, held for another order or simply recorded incorrectly. Replenishment changes will not fix all of those causes. Log the reason and affected item so the team can see recurring patterns.
Use a reorder point as a starting estimate
A simple planning example is average daily demand multiplied by lead time, plus safety stock. At four units a day, five days of lead time and six units of safety stock, the illustrative point is 26 units. This is not a recommended setting: variable demand, supplier reliability, order sizes and service requirements may call for a different method.
Review the assumptions
Use actual receipt dates rather than the supplier's quoted lead time alone. Check seasonality, minimum order quantities and cash or storage constraints. Agree how on-order stock and reservations affect the quantity used for a reorder decision. Otherwise two teams may act on different stock positions.
Keep an accountable review
Assign someone to review shortages, late deliveries and changed assumptions regularly. In a VasKem demonstration, check the records, alerts and exports available for that process. Automatic forecasting, purchase-order creation and supplier scorecards should be separately confirmed, not inferred from an inventory screen.
