When you need it
Use when deciding whether to hold, share or order spare parts for operating assets. Review after failures, supplier changes or obsolescence notices alter the balance between outage exposure and stock costs.

How to use this template
What it helps you decide
The assessment ties stock decisions to compatibility, lead time and service consequence. It prevents apparently available inventory from being counted as useful when parts are reserved, deteriorated or incompatible with installed equipment.
How to complete it
- Verify Part / revision against the asset bill of materials and Compatible assets. Check interchangeability evidence rather than inferring suitability from appearance or similar descriptions.
- Record Failure consequence, Usage history and Lead-time evidence. Distinguish indicative supplier availability from commitments and assess how a shortage affects service restoration.
- Explain Holding rationale, Preservation need and Review / obsolescence. Use the owner's approved policy; the template supplies no automatic reorder quantity or statistical stock formula.
Who prepares and reviews it
A maintenance planner or spares engineer prepares it with stores, procurement and operations. Technical specialists verify compatibility and preservation; the asset owner or delegated inventory authority approves holding policy and expenditure.
A mistake to avoid
Counting every stored component as usable stock ignores shelf-life, preservation, reservation and revision compatibility, potentially overstating the operator's ability to recover from failure.
Illustrative example
Illustrative example: a facility finds a spare controller in stores for an important packaged unit. The assessment shows that the installed controller uses a different revision and compatibility is unconfirmed. Maintenance seeks supplier evidence before treating the spare as available recovery capacity or purchasing a replacement.
