Order quantities are based on item / quantity original commitments agreed to by the customer. Orders canceled by the customer are excluded from the metric. Order changes initiated by the customer and agreed to by the supplier supersede original commitments and form a new comparative basis for the metric. This metric has no "timing" element, such that orders deliberately split by the supplier should still be considered “in full” so long as all metric criteria are met. In some cases, such as for supplying bulk materials, committed quantities refer to a range that is acceptable to the customer rather than a strict value.
