The 2026 enterprise agentic AI procurement playbook resolves to a six-stage sequence that integrates the build-vs-buy-vs-partner decision, the 60-question agentic AI RFP, the GAUGE governance scoring, the four-vendor comparison, and the EU AI Act compliance scaffolding into one operational track. Most enterprises in 2026 run these as separate work streams owned by separate functions, which produces structurally inconsistent procurement records and substantial duplicate effort. The integrated six-stage track ships in 8 to 10 weeks for standard environments and produces an audit-defensible per-deployment procurement artifact that satisfies the EU AI Act Article 9 risk-management system requirement by construction.

Procurement playbook claim is scoped to enterprise agentic AI procurement specifically. The six-stage sequence is portable to adjacent procurement categories (data platforms, observability stacks) but is not optimised for them. 60-day review cadence. Watches: (1) major changes to any of the four constituent frameworks (build-vs-buy criteria, the 60-question RFP, GAUGE dimensions, vendor landscape), (2) regulatory enforcement that materially changes the documentation bar at any stage, (3) procurement-platform vendors that ship native integration of any combination of the constituent frameworks (would compress engineering work substantially).
