Situation: A product manager requests daily updates during a warehouse migration I'm leading as a data engineer.
Proposal — cadence & format:
- Daily 10–15 minute written digest (sent at 4pm) + optional 15-minute stand-up Mon–Fri for Q&A.
- Weekly executive summary (Mon) for broader stakeholders.
Daily digest structure (subject line: “Warehouse Migration — Day X — Green/Amber/Red”):
- Snapshot (1 line): overall status (Green/Amber/Red) and % complete.
- Metrics (bullets): percent complete (by milestones), data cutover progress (tables migrated / total), ingestion success rate (%), processing/job success rate, lag/backlog size, consumer-impacting queries failing.
- Blocker log (table): blocker, owner, impact, ETA to resolve, escalation status.
- Risks & mitigation (mini heatmap): top 3 risks (likelihood × impact), current mitigation steps.
- Actions for tomorrow: specific tasks and owners.
- Artifacts links: runbooks, migration checklist, dashboards (Grafana/Datadog), test plans, rollback plan, changelog.
Metrics & artifacts to include:
- Percent complete by milestone (schema migration, ETL cutover, validation, decommission)
- Data validation stats (row counts, checksums, row-level diffs)
- SLA/Near-real-time latency, job durations
- Consumer acceptance tests status
- Link to live dashboards, CI/CD logs, incident board, and post-mortem template
Escalation process for critical blockers:
- If blocker is P0 (data loss, production outage, missed SLA) notify immediately via designated Slack channel + page on-call lead.
- In digest mark blocker as “Escalated” and include remediation owner and ETA.
- Trigger 15-minute emergency war room (engineer, on-call, PM, infra/SRE) until mitigated.
- After resolution create a blameless incident note and update rollback/mitigation docs.
Reasoning: Short, consistent daily digests reduce noise, provide transparency with actionable items, and keep escalation pathways explicit so critical issues get immediate attention without overloading stakeholders.
