Technical Risk Assessment and Mitigation Questions
Technical risk assessment and mitigation covers systematically identifying, prioritizing, and addressing potential failure modes and implementation pitfalls across architecture, integration, data migration, scalability, performance, security, third party dependencies, and team skill gaps. Candidates should demonstrate methods for analyzing and categorizing risks, such as fault tree analysis and failure mode and effects analysis, and describe practical mitigations including staged rollouts, canary deployments, redundancy and failover, rollback and contingency plans, increased testing, capacity planning, security hardening, monitoring and observability, runbooks, and training or vendor support. Interviewers expect discussion of validation strategies for mitigations, including dry runs, experiments, load and performance testing, chaos engineering, staged deployments, and monitoring driven verification before full production release. Strong answers will show how to prioritize by likelihood and impact, trade off cost and schedule, define measurable success criteria, and iterate on mitigations based on operational feedback.

How would you create and maintain runbooks and on-call playbooks across multiple product teams as a Solutions Architect? Outline an operational process, ownership model, validation cadence, templating standards, and integration with incident postmortems and CI/CD pipelines.

A distributed system using message queues observes message duplication under high throughput. Design mitigation strategies to provide at-least-once or exactly-once semantics, discuss trade-offs in complexity and cost (idempotency, deduplication store, transactional outbox, broker features), and propose validation tests to ensure correctness under production load.

Create a testing matrix for a distributed feature that touches 20 microservices. Include unit, component, contract, integration, end-to-end, load, chaos, and canary tests; specify where each test runs (CI, staging, production), who owns them, and how to prevent flaky tests from blocking releases.

A third-party payment processor handles 80% of your transactions and experiences intermittent failures during peak hours. Architect a mitigation plan to reduce customer impact without replacing the provider: include routing/fallback logic, parallelization or queuing, async retries with deduplication, and a reconciliation process to ensure financial correctness.

You're on a sales call discussing a 6-month cutover timeline. You identify several technical risks likely to delay delivery (integration complexity, data migration, third-party readiness). How do you communicate these prioritized risks and mitigations to the customer and internal sales team while preserving trust and deal momentum? Provide phrasing and negotiation strategies you would use.
