Meaning
Strategic buffer stocks or forward contracts secure the availability of critical components against the risk of extended supply chain delays. Implementation of lead time hedging allows a production facility to continue operating even when a primary supplier faces a disruption. This approach focuses on the most vulnerable parts of the bill of materials.
Inventory Cushion
Maintaining extra stock of long lead items provides a safety net against fluctuations in shipping times. Success in lead time hedging depends on accurately forecasting the maximum possible delay and sizing the buffer accordingly. The cost of carrying this inventory includes warehouse space and the risk of obsolescence.
Supplier Commitment
Binding agreements for future delivery slots ensure that a manufacturer has a guaranteed place in the production queue of its vendors. Effective lead time hedging uses these contracts to bypass the spot market during periods of high demand. This stability allows for more accurate production planning and better customer service.
Cost Protection
Paying a premium for guaranteed availability reduces the risk of expensive line shutdowns. Calculations for lead time hedging must weigh the price of the hedge against the potential loss of revenue from a stalled factory. When a supplier demonstrates a consistent rate of delivery, the size of the hedge can be reduced to save capital.
A well managed program adjusts these levels as market conditions change.
