What it is#
Lead time is the total span from placing an order to having the goods available; long lead times are extended delays — weeks or months for overseas sourcing, slow procurement, or constrained production.
The inventory cost#
Longer lead times force businesses to hold more safety stock to cover demand over the wait, directly raising holding costs — safety stock scales with the square root of lead time:
They also cut agility: you can’t respond quickly to demand shifts, and the risk of stockouts and missed deliveries climbs.
Variability is worse#
An unpredictable lead time is more damaging than a long-but-stable one, because its variance widens the buffer needed. Causes include geographic distance, production constraints, poor visibility and transport disruptions.
