An MVP that proves one workflow usually lands in six to ten weeks when data access is quick. That covers scope, prototype, and a limited production try with a pilot group. Full deployment across sites, SSO, and hardened logging often needs twelve to twenty weeks. Complex multi agent systems with several host integrations stretch longer because change control, not coding, owns the calendar. Hampton defense suppliers should expect extra weeks for network findings and certification packets. We write the timeline with those gates, not against them.
MVP means one job end to end with measurable scores. It is not a chat demo on synthetic text. We insist on your documents or call samples under NDA so accuracy claims mean something. Parallel tracks help. While engineers wire connectors, operators write the policy for when the model must escalate. That dual track is how logistics phone agents and HR pre-screen tools hit calendar targets without skipping design reviews.
Timeline slips mostly from late data, vague success metrics, or missing system owners. We freeze those items in the first two weeks. Holidays, freezes on production changes, and audit blackouts get plotted up front with your PMO. Stabilization after launch is two to four weeks of active tuning and is part of the plan, not a surprise fee. After that, improvements move into a backlog with monthly scorecards. Teams that treat AI as ongoing capacity, not a one shot project, keep speed after the first release.
