What change-freeze windows should we avoid when enabling new Mode features this month?

To prove a Lambda update improved productivity without increasing risk, track productivity KPIs like Task Completion Rate, Cycle Time, and Output per Hour and risk KPIs such as Error Rate, Defect Density, System Downtime, and Customer Satisfaction (CSAT). A successful update will show improvement in the productivity metrics while keeping risk metrics stable or decreasing them.

To export Superset logs to a Security Information and Event Management (SIEM) system with least-privilege scopes, use a log shipper to collect logs from Superset's standard output (stdout) and its file-based logs. This approach avoids granting Superset direct access to your SIEM. The specific implementation depends on your deployment environment (e.g., Docker, Kubernetes).

Rollback plan
A Metabase rollback depends on the deployment method (e.g., Docker, JAR). For any method, a full application database backup is the most reliable way to revert.
Phase 1: Pre-rollout preparation

• Establish a performance baseline: Before deployment, measure average dashboard load times, query execution times, and resource utilization (CPU, memory) during peak usage.

Phase 2: Execution and monitoring

• Monitor post-upgrade performance: Use monitoring tools (like VisualVM, JMX) or Metabase's built-in usage analytics to watch for performance regressions.

Phase 3: Post-mortem and relaunch

• Conduct root cause analysis: After the rollback, investigate the specific queries or dashboards causing the issue. Use the Metabase usage analytics to identify resource-intensive queries.

Communications plan
A clear, proactive communication strategy manages expectations and maintains user trust.
Before rollout

• Notify users: Inform all users of the upcoming upgrade and the potential for temporary performance changes. Clearly state the maintenance window.

During an incident

• Initial notification (within 15 minutes)
• Rollback decision (within 1 hour)
• Resolution update (as soon as the rollback is complete)

After the incident

• Post-mortem summary: Publish a summary explaining the issue, the actions taken, and the improved plan for the next deployment. This builds trust and shows accountability.
• Lessons learned session: Schedule a review session with key stakeholders to discuss the incident and gather feedback on the rollback and communication process.

To restrict Power BI features to a pilot group, combine the Tenant Settings within the Microsoft Fabric Admin portal with Azure Active Directory (AAD) security groups. For controlling feature access inside specific reports, use Row-Level Security (RLS) in Power BI Desktop.

To prove that the Data Cloud update improved team productivity without increasing risk, you need to track and analyze a balanced set of Key Performance Indicators (KPIs). This involves monitoring metrics across three key categories: Operational Efficiency, Data Quality & Reliability, and Business Impact & Adoption.
