Why a Customer Should Keep a Spare Parts Inventory

  • Minimize downtime and keep essential equipment running without interruption.
  • Parts may be out of stock at the factory.
  • Lead time on non-stock parts can be too long for your application.
  • Critical spares – if you have a need for a spare part that is critical to your operations and the predominant failure mode is unpredictable, catastrophic failure, then your planning horizon is effectively zero and so you should definitely hold a spare part.
  • A spare parts inventory should consist of any items that could cause extended downtime if a failure occurs.
