Why a customer should keep a Spare Parts inventory

  • Minimize down time and keep essential equipment running without interruption
  • Parts maybe 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
