Why Keep a Spare Parts Inventory

Customers tell us that keeping an inventory of spare parts on hand makes for efficient operation. Such an inventory can:

  • Minimize downtime and keep essential equipment running without interruption
  • Insure against parts that may be out-of-stock at the factory
  • Consist of any items that could cause extended downtime if a failure occurs
  • Drastically minimize lead time on the replacement of non-stock parts
  • Ensure you are never short on critical spare parts – if you need a spare that is critical to your operations and the predominant failure mode is an unpredictable catastrophic failure, then your planning horizon is effectively zero. You would do well to maintain a spare part.
