Assign data ownership
Someone should be accountable for each important field and dataset.
Use controlled definitions
Condition, status, asset type and location codes need shared meaning.
Preserve history
Overwriting old values can destroy the evidence needed to understand deterioration and past decisions.
Audit quality selectively
Completeness, duplication, impossible dates and orphan records can be checked without inspecting every field manually.
Scope. This page explains asset-management concepts, not operating procedures for critical infrastructure. Inspection methods, intervention thresholds and safety decisions must follow the asset owner’s standards, local rules and qualified professional judgement.
