For CTOs: Architecture & Technical Lifecycle
Lifecycle starts with a decision ledger, not a backlog dump. Every major choice on models, queues, and identity gets a written trade-off with an expiry date for revisit. That habit keeps temporary spikes from becoming permanent debt. Arlington IT leads can audit the ledger without reverse-engineering tickets.
Kickoff freezes interfaces. APIs, events, and storage schemas become the contract between our builders and your teams. Changes go through a short RFC so side effects stay visible. Continuous freestyle coding against live prod data is banned for good reason.
Environments stay honest. Dev uses synthetic and scrubbed sets. Staging mirrors auth delays and network limits you actually face. Production only accepts signed artifacts with provenance. Canary percentages scale with confidence, not calendar hope.
Governance covers model cards, evaluation boards, and access reviews. Drift checks fire when label distributions shift more than set bands. Prompt and weight version pins travel with each deployment. On-call rotations include both app and ML reply paths so paging never orphan the second half.
Exit readiness matters as much as entry. Handback includes IaC, secrets map, dashboards, and a sixty-day warmup window. You choose retain, co-run, or full internal ownership without scramble. That posture earns trust with defense-adjacent buyers who plan for contractors to leave clean.
