Restocking a variant can respond to quick sales or unfulfilled requests. The decision must take into account the delivery time and the remaining commercial period. A product requested today could come when demand conditions have already changed.
I propose to distinguish the observed demands from the quantities that are expected to sell. A repeated interest is useful information, but comparison requires availability, alternatives and costs of the order. The composition of the remaining variants can also influence the value of the reassortment.
In a hypothetical example, one size ends early while others remain available. The reorder can complete a still usable proposal, or arrive too late. The reading must include the time of delivery and what the store may offer in the following period.
The verification compares the forecast and the result of the added lot, keeping it recognizable compared to the initial purchase. Reassortment makes sense when the observed speed is read along with the calendar. This distinction makes it possible to avoid orders motivated only by the past success of the variant.
