Critical spares should be governed like uptime insurance: visible, current, and sized for the things that really fail.
A spare part is only helpful if the team can find it in time.
Field takeaways
- Build the spares list from failure history and lead time, not habit.
- Review ownership and stock levels every month.
- Keep recovery-critical parts close to the work order process.
Base the list on failure history
The most useful spares list grows out of past incidents and replacement lead times. It should reflect what actually slows recovery, not what happens to be left over from last year’s project.
Keep ownership and access obvious
If nobody knows who signs for the spare or where the last unit is stored, the inventory may as well not exist. Recovery works best when the path from failure to replacement is already documented.
Review spares the same way you review maintenance
Monthly checks should show stock status, missing labels, aging inventory, and any part that would now be too slow to replace. That makes the list a living control, not a dusty shelf.
