A method includes calculating model probabilities and a ranked list of locations and receiving a selection of a plurality of the ranked locations. The method also includes receiving actual item count data from at least a subset of the selected locations and comparing the actual item count data to a corresponding inventory record. The method further includes outputting a discrepancy indication based upon a discrepancy between the actual item count data and the corresponding inventory record.
