# Architecture Review Checklist

## Business fit
- What capability and outcome does the solution enable?
- Why is this pattern proportionate to the problem?
- Which assumptions would materially change the design?

## Data and integration
- Where is each authoritative record owned?
- How are identity, effective dating, lineage, quality, and retention handled?
- Are APIs, events, batch, and orchestration choices justified?

## Non-functional design
- Security, privacy, availability, resilience, performance, scale, and recovery
- Observability, auditability, configuration, change, and lifecycle management
- Vendor, environment, network, and rate-limit dependencies

## Operating model
- Who owns product, platform, data, security, delivery, and support decisions?
- How will the solution be monitored, supported, changed, and retired?
- What evidence is required for architecture and production approval?
