Identity comes first
Every maintainable asset or asset group needs a stable way to be identified across drawings, work orders, inspections and financial records.
Location must be usable
Coordinates, route references, facility hierarchy or other location systems should be precise enough for field and office teams to refer to the same asset.
Attributes support decisions
Installation date, material, capacity, manufacturer, inspection history and criticality can be useful when they are kept current and defined consistently.
A register is not a document graveyard
The point is decision support. Duplicate, stale or ambiguous records can be worse than a smaller, well-governed dataset.
