For CTOs: Architecture & Technical Lifecycle
The lifecycle starts with a constrained problem statement, not a platform bake-off. Kickoff locks success metrics, data contracts, and non-goals before any model subscription is signed. Discovery workshops spell integration points with LMS, CRM, claims, or ERP systems already live in Virginia shops. Threat models cover prompt injection, data leakage, and cost runaway in the same pass as latency targets.
Design decision points stay visible. Retrieval versus fine-tune. Rules before generation. Single agent versus multi-step graph. We document the trade-off, the reject path, and the date to revisit. Governance boards get a one-page ARB note they can archive. This prevents silent architecture drift six months later when a vendor raises prices.
Build phases produce slim vertical slices. Observability hooks arrive with the first deploy, not during panic. Staging uses scrubbed data shapes that still exercise ranking and exception paths. Promotion rules require baseline-beating metrics under production-like traffic. Your team co-owns the repository from week one so knowledge transfer is continuous, not a final dump.
Production is a lifecycle gate, not a finish line. Model versions pin. Prompts version. Feature flags control exposure by site or brand. Rollback scripts exist before marketing announcements. Incident runbooks name on-call, severity, and customer notice paths. CTOs in Lynchburg get systems that behave like the rest of the stack, not special snowflake labs.
Exit criteria include documented ownership transfers. Accounts, keys, dashboards, and vendor tickets move fully under your domains. Retainer options stay optional. That independence is intentional architecture, not a sales afterthought.
