Key takeaways
Short answer: An asset tag is the unique, durable identity for a machine. Every work order, failure record, spare part, and OEE number attaches to it. When tags are missing, duplicated, or inconsistent, all of that data fragments — and no software can fix a broken foundation. Tagging is cheap, foundational, and routinely neglected. See also maintenance engineer vs reliability engineer.
If the same machine is recorded under two tags, its history splits and its real failure rate hides. If a tag is missing, work gets logged to "the line" and asset-level analysis becomes impossible.
It is unglamorous and the cost of skipping it is invisible until you try to analyse failures and find the data fragmented. By then it is expensive to fix retroactively.
OEE is reported per asset. Without clean tags, OEE rolls up to meaningless line totals and you cannot find the bad actor dragging the number down.
See how Fabrico captures this automatically on your lines — explore OEE for manufacturing or book a demo.
Yes — it is the identity every other record depends on.
Unique, durable, consistent, one per asset.
Yes but retroactive cleanup is costly; do it early.
CMMS and OEE system must use identical IDs.
