Evidence worth collecting before the condition changes
- Existing asset list or equipment naming
- Work orders, notebooks, spreadsheets, invoices, or technician reports
- Common failure descriptions and spare-parts records
- Who owns data entry and verification
- Current preventive-maintenance records
Questions that improve the diagnosis
- Can one asset be uniquely identified across records?
- Can a repeat failure be found without relying on memory?
- Do records distinguish symptom, cause, action, parts, downtime, and verification?
- What minimum fields would improve the next maintenance decision?
What not to conclude too early
- Starting with a large CMMS data migration before cleaning asset identity
- Creating duplicate asset names across departments
- Recording only 'repaired' without failure/action detail
