An item represents the product identity. An item revision represents a specific version of that identity.
This difference is simple on paper but critical in real PLM usage. If teams do not understand the difference, they will struggle with change control, release management, and traceability.
Simple example
If a part number identifies a bracket, that is the item. If the bracket changes over time, each controlled version becomes an item revision. The identity remains connected, but the revision history preserves what changed.
Why it matters
- Supports controlled versioning
- Preserves product history
- Improves release and change traceability
- Lets teams refer to a product consistently while still tracking evolution
