An on-call engineer spends hours every week performing a repetitive, scriptable recovery operation. The team wants to reduce operational toil. Which approach best fits?

1. Automate the recurring operation and measure the reduction in manual work.
2. Conduct a blameless postmortem with owned corrective actions.
3. Run controlled failure-injection exercises with clear safety limits.
4. Reserve paging for actionable symptoms and route lower-urgency signals appropriately.
