Purpose
Evaluate event outcomes, preserve technical knowledge, implement corrective actions and improve future asset and shutdown performance.
Scope
- Final performance consolidation — cost, schedule, safety, scope and quality
- Post-event review and technical failure/condition review
- Benefits realisation verification
- Asset and maintenance strategy updates
- Process improvement action implementation
- Final event report, archive and return of learning to the STO lifecycle
Phase Gate
Every phase closes at a formal phase gate. Work may proceed to the next phase only when the accountable authority accepts the required outputs, the outstanding conditions and the residual risks. The gate is a decision, not a formality — an unaccepted gate means the event is not ready to move on.
Process Steps
- 01
Consolidate Final Event Performance

Key Performance Indicators
| KPI | Why It Matters | How To Measure | World Class | Benchmark | Typical |
|---|---|---|---|---|---|
| Post-event review held within 4 weeks | After four weeks the team has dispersed and the detail is gone — the review becomes folklore. | Events with a documented review inside 4 weeks ÷ total events. | — | 100% of events | — |
| Improvement actions closed on time | Lessons that never become closed actions are the reason the same problems recur every event. | Actions closed by due date ÷ actions raised. | — | >90% | — |
| Asset strategies updated from event findings | Opening an asset is the best condition data you will ever get — not using it wastes the outage. | Assets with revised PM/strategy ÷ assets where findings warranted a change. | — | 100% of applicable assets | — |
| Benefits verified against the charter | Unverified benefits let poor events be reported as successes. | Objectives measured with evidence ÷ objectives declared in the charter. | — | 100% of stated objectives | — |
| Next-event scope candidates transferred to the CMMS | Deferred work that leaves the system reappears as a breakdown. | Deferred/follow-up items raised in the CMMS ÷ items recorded at closure. | — | 100% of deferred work | — |
