A proposed workflow
The sequence below is a starting design, not a claim about the current operation.
- 01Create a dependable asset hierarchy for a bounded areaDefine evidence and the exception path
- 02Standardize request and priority intakeDefine evidence and the exception path
- 03Issue and complete controlled work ordersDefine evidence and the exception path
- 04Record action, parts, failure, and verificationDefine evidence and the exception path
- 05Review repeats under comparable conditionsDefine evidence and the exception path
- 06Adjust preventive work through approved maintenance decisionsConfirm ownership and handover
Design
Data inputs
Use the minimum information needed and define its source and retention.
| Reference | Input or decision to establish |
|---|---|
| 01 | Asset and criticality |
| 02 | Request, response, start and finish times |
| 03 | Failure symptom, finding, cause and action |
| 04 | Operating context and preventive schedule |
Design
Human responsibilities
Automation routes information; accountable people retain operational decisions.
01Production reports observable symptoms
Use a representative example to confirm the cause, owner, decision rule, and exception path.
02Maintenance triages and records findings
Use a representative example to confirm the cause, owner, decision rule, and exception path.
03Planner controls preventive schedule
Use a representative example to confirm the cause, owner, decision rule, and exception path.
04Reliability or operations owners approve changes
Use a representative example to confirm the cause, owner, decision rule, and exception path.

Limitations
Information workflow changes are not machine repair, PLC programming, reliability engineering, or functional-safety work. Downtime may be driven by factors outside the digital scope.
