Summary
In short
- A spares criticality review is a review used in KnowMaintain that decides which spare parts must be held on site based on lead time and asset criticality. It is built against ISO 55001 cl.8.1 and forms part of the Reliability and Predictive Maintenance programme.
- Run yearly. Carried out by the planner with procurement.
- The template holds 44 fields across 4 sections, with parts assessed repeating for each entry.
- Scoring is stocking decision.
- ISO 55001 is asset management systems. The international standard for getting value from physical assets across their whole life. Underpins the maintenance templates.
- It connects to the rest of the library: links Asset, Parts.

When to use it
When to use it, and when not to
This review is one step in a larger programme. Using it for work that belongs to a neighbouring template produces records that are hard to report on later.
Use it for
- The event or activity this review covers has occurred, or is about to
- A new record is needed; each one gets its own ID in the form SCR3-2026-000
- You are running the Reliability and Predictive Maintenance programme and this is one of its steps
- A linked record needs this one to exist: links asset, parts
Not for
- Equipment FMEA, which works through how an asset could fail, what the effect would be and how likely it is to be detected.
- Reliability Centred Maintenance Study, which decides the right maintenance strategy for each failure mode, from run to failure through to condition monitoring.
- MTBF Review, which reviews mean time between failures for an asset or asset class over a period.
- Anything outside KnowMaintain, which belongs in the workspace that owns that process

FAQ
Frequently asked questions
What is the spares criticality review template based on?+
It is built against ISO 55001 cl.8.1. ISO 55001 is asset management systems. The international standard for getting value from physical assets across their whole life. Underpins the maintenance templates. ISO is international Organization for Standardization. A voluntary international standard. Widely adopted, often required by customers, and certifiable where a management system standard.
What sections does the spares criticality review contain?+
There are 4 sections: header, parts assessed, related records, result. Together they hold 44 fields, 26 of which are required.
How often is a spares criticality review raised?+
A new record is raised at the review interval, and after any trigger event. Each one is given an ID in the form SCR3-2026-000, so it can be traced and referenced from other records.
Which programme does the spares criticality review belong to?+
It is part of Reliability and Predictive Maintenance. Intervals set by failure behaviour rather than by the calendar.
How is a spares criticality review scored?+
Scoring is stocking decision. Scores exist to make the form tell you something, not to produce a percentage for its own sake.
Can the spares criticality review template be changed?+
Yes. Every field, option, score and conditional rule is editable, and the links to other templates come with it. Most teams install it as it is, run it for a cycle, then adjust.
The agents
What the agents do with it
The form is the easy part. Keeping it current, routing it to the right owner and holding the evidence together is the work that actually slips.
Holds the spares criticality review library against your registers, routes each record to its owner, and keeps the evidence trail together.
Coordinates the crew, rolls completion and exceptions into one view, and holds every write for your approval before it touches a record.
This template lives in KnowMaintain — asset maintenance. Work orders, planned maintenance, calibration, reliability and shutdowns.
