Signals of expertise

Quality

★Alternatives-considered with explicit trade-offs
★non-functional requirements and failure-mode analysis
★rollout/migration and observability
★right-sized scope

Common mistakes

Pitfalls

×Jumping to one solution with no alternatives
×ignoring scale/security/failure
×no rollout/migration plan
×diagram-free hand-waving

One tool. One finished ready-to-use technical design spec.
