AI for Technical Architecture Design & Incident Post-Mortems
Master systems-level engineering: Scaffold Architecture Decision Records (ADRs), conduct STRIDE threat modeling with AI, and analyze production incident logs for blameless post-mortems.
Key Takeaways
- Architecture Decision Records (ADRs) document technical context, evaluated alternatives, and deliberate tradeoffs before code is written
- AI-assisted threat modeling (STRIDE) systematically evaluates spoofing, tampering, repudiation, information disclosure, DoS, and elevation of privilege
- During major production outages (SEV-1), feeding sanitized log dumps into AI accelerates root cause hypothesis generation and timeline reconstruction
The Diagnostic Context
Staff and Principal Engineers are evaluated on architectural foresight and incident resilience. Using AI to stress-test architectural decisions against the STRIDE threat model and synthesize complex production incident timelines enables engineering teams to build robust, resilient distributed systems.

Copyable Prompt: Architecture Decision Record (ADR) Generator
You are a Principal Software Architect. Draft a formal Architecture Decision Record (ADR) for the following engineering decision: Context & Problem Statement: "[Insert Problem: e.g., Choosing between Kafka vs RabbitMQ vs AWS SQS for order event streaming across 12 microservices]" Format using the standard Michael Nygard ADR format: 1. Title: ADR-[Number]: [Concise Decision Title] 2. Status: Proposed / Accepted 3. Context: What technical constraints, latency requirements, throughput expectations, and organizational factors drive this decision? 4. Decision: State the chosen architecture clearly. 5. Evaluated Alternatives: Detail at least 2 alternative approaches with their pros and cons. 6. Consequences: Detail positive outcomes, negative trade-offs, and ongoing operational maintenance overhead.
Try This Right Now
Draft an ADR for a recent technical choice in your organization (e.g., choosing a database, caching layer, or message broker) using the prompt above. Review the trade-offs and operational consequences section.
Tip: Knowledge only becomes capability once you run the prompt yourself.
