The perfect order rate is the share of orders delivered on time, in full, damage-free and with correct documentation. Because those components multiply rather than average, four processes each running at 95% produce a perfect order rate near 81%.

Frequently asked questions
How is the Perfect Order rate calculated?
The Perfect Order rate is the product of its four component pass rates — on-time × in-full × damage-free × correct-documentation — because an order only counts as perfect if it clears every one of those hurdles at once. For example 0.96 × 0.94 × 0.98 × 0.93 ≈ 0.822, so about 82% of orders are perfect even though every single metric looked strong on its own.
Why is the Perfect Order rate lower than each individual metric?
Because you multiply four numbers that are each below 100%, and multiplying sub-100% figures always gives a smaller result than any one of them. An order must be on time AND in full AND undamaged AND correctly documented simultaneously, so strong individual metrics still compound into a noticeably lower combined figure.
What counts as a "perfect order"?
An order delivered on the date promised, with the full quantity in one shipment (no backorder), in saleable condition (no transit damage), and with fully correct invoicing and paperwork (no billing query). Failing any single dimension means the order is not perfect, even if the other three were flawless.
