Perfect order rate

The probability that an order is on time, complete, undamaged and correctly documented, all at once.

Perfect order rate = On-time % × Complete % × Damage-free % × Accurate documentation %

Each component looks healthy on its own dashboard. Multiplied together they show what the customer actually experiences: four processes at 95 to 99 percent leave roughly one order in ten with something wrong.

The multiplication is an approximation that treats the four failures as independent. If you can count orders that passed every check directly from your order data, use that count instead; it is the true figure.

How to read it

Use it to choose where to work next. Raising the weakest component by one point improves the result more than polishing a component that is already at 99.
