Situation: Sprint focused on migrating 50 pipelines to a new platform. At 2pm, production incident: critical revenue dashboard showing zeros; SLA breach risk. Task: Resolve incident without abandoning migration; no hero culture. Action: (1) Triaged with lead—root cause: upstream CDC job failed silently. (2) Delegated migration tasks to pair; I took incident. (3) Fixed CDC (schema drift), backfilled, validated. (4) Post-incident: added validation step to pipeline; documented in runbook. (5) Caught up migration next sprint; communicated timeline shift to stakeholder. Result: Incident resolved in 2 hours; dashboard recovered. Migration completed 3 days later than planned; stakeholder informed. Implemented validation to prevent recurrence.
