Prerequisite Checklist

blocking

team

Team at 'experienced backend team' maturity level

This scenario is rated 'experienced backend team' complexity. Engineers with 2+ years of production backend experience, including database tuning and monitoring.

Gap signal: Team frequently reaches for external help during incidents or struggles to debug multi-system issues independently.

blocking

process

Failure mode awareness and runbooks

The team must understand the 6 documented failure modes for this scenario: queue_backlog_accumulation, thundering_herd, disk_io_saturation, slow_consumer. Each should have a documented detection procedure and runbook.

Gap signal: The team has no documented runbooks for the scenario's failure modes or cannot name them without reference material.

blocking

monitoring

Production-grade observability stack

The scenario requires real-time metrics, structured logging, and distributed tracing on all critical components. Alerting must be configured before going live.

Gap signal: No dashboards exist for the critical path metrics in the scenario.

infrastructure

Minimum team maturity: Experienced Backend Team

This scenario has high operational complexity. It is recommended for Experienced Backend Team teams or higher.

Gap signal: The requirement 'Minimum team maturity: Experienced Backend Team' is not yet in place.

infrastructure

Runbooks and alerting for high-severity risks

5 high-severity risks identified. Each requires a documented runbook, alerting threshold, and on-call response procedure before running in production.

Gap signal: The requirement 'Runbooks and alerting for high-severity risks' is not yet in place.

infrastructure

Event stream operations expertise

This architecture includes event stream infrastructure (Kafka, Kinesis, or similar). Operations requires consumer group management, partition assignment, dead-letter handling, and lag monitoring.

Gap signal: The requirement 'Event stream operations expertise' is not yet in place.

blocking

infrastructure

Mitigation for 4 high-risk topology node(s)

Nodes with high or critical risk exposure: Event Streaming, Time-Series Metrics, Redis, Slow Consumer. Each requires documented mitigation before production deployment.

Gap signal: No mitigation strategy is documented for the high-risk nodes in the topology.
