For CTOs: Architecture & Technical Lifecycle
Lifecycle opens with a constrained problem statement, data inventory, and success thresholds signed by ops and security. We refuse open-ended AI roadmaps that skip gateway, identity, and rollback design. Architecture decision records capture why batch beats real-time or why a managed model API beats self-host for a given stage. Those records travel with the change package your CAB already expects.
Discovery spikes measure label quality, PII density, and integration friction on real samples. Participants include the subject-matter owners who will live with false positives. Output is a build-or-wait recommendation, not a default yes. Waiting is success when data cannot support the claimed outcome yet.
Build phases separate ingestion contracts, model or rule cores, application UX, and observability. Each phase has demos against frozen acceptance cases. Parallel work only happens when interfaces freeze early enough that teams do not thrash. Chesapeake IT groups with limited release windows need this discipline more than greenfield startups.
Governance covers model cards, prompt or feature change reviews, and incident paths if outputs degrade. Ownership names both an engineering contact and a business product owner. Drift is treated as a production incident class, not a research note. That posture matches how you already handle performance regressions on customer-facing software.
Exit criteria for production include canary thresholds, runbooks, cost alerts, and a decommission plan if value fades. CTO review focuses on operational debt created, not only accuracy slides. We leave you with systems your team can run if engagement scope ends after stabilisation.
