For CTOs: Architecture & Technical Lifecycle
CTO review starts with boundaries. Model services stay replaceable while the data contracts and IAM story remain the system of record. Kickoff freezes the decision log for retrieval scope, human-review thresholds, and cost ceilings. Trade-offs are written where ops can find them at 2 a.m.
Lifecycle stages are discovery, contract hardening, gated pilot, canary, and full traffic. Each gate has exit criteria tied to latency, miss rate, and dollar per successful call. Governance meetings review flags rather than anecdotes. Drift owned by product, not a hallway chat. You get fewer heroic weekends.
Build vs buy shows up early. Managed model APIs win when patches and hardware staff are thin. Self-host wins when network isolation or IP policy demands it. We document the fork so budget owners see the reason, not just the invoice. Changing forks later stays possible when interfaces stay thin.
Technical debt rules ban prompt sprawl in application code. Templates version like any other artifact. Feature flags wrap every generative path. Rollbacks never need a schema rewrite. Legacy adapters fail closed with clear alerts. That stance matches multi-vendor yards where one bad change can halt morning boards.
Exit planning is part of architecture. Handoff packs include diagrams, secrets rotation notes, and owner rosters. Shadow mode after cutover catches silent quality slips. CTOs leave with a system a new hire can reason about. That is the lifecycle bar we accept on every Virginia engagement.
