The 2026 digital-transformation RFP that includes agentic AI procurement extends the existing 60-question RFP playbook (/the-enterprise-agentic-ai-rfp-60-questions/, 38 Copilot citations) with 15 UX assessment questions across five categories (interaction modes; error-handling and confidence-communication; accessibility against WCAG 2.2 + Section 508 + EN 301 549 + assistive-technology compatibility; multi-user and cross-device continuity; design-system extensibility), producing a 75-question total RFP that the buying committee uses with separate reviewer assignments (UX team plus accessibility office plus design-system stewards review the UX section); the procurement-mature pattern asks the vendor to demonstrate the answers to error-handling, accessibility, continuity, and extensibility questions rather than describe them, surfacing the gaps between strategic narrative and product capability before the MSA negotiation.

Anchored on (a) the existing /the-enterprise-agentic-ai-rfp-60-questions/ playbook the 15 UX questions extend (38 Copilot citations in 3-month window ending 25 May 2026); (b) WCAG 2.2 (latest W3C accessibility recommendation), Section 508 (federal-civilian US accessibility), EN 301 549 (EU accessibility standard); (c) procurement-team observation of UX-dimension gaps in 2025-2026 agentic AI vendor RFPs (the dimension most often surfacing at year-one user-adoption review rather than at RFP). The 15 specific questions are derived from standard enterprise UX-procurement-practice extended to the agentic AI vendor structure plus the 2026 EU AI Act Articles 13 (transparency) and 14 (human oversight) requirements; the question set is not from a published external reference (this is procurement-team practice synthesised into a checklist). 60-day review cadence (26 Jul 2026). Trigger conditions: (1) EU AI Act implementing acts shipping mandatory technical standards on agent-user interaction (Article 13 transparency, Article 14 human oversight) would standardise some of the question set and warrant a refresh moving claim toward Partial; (2) WCAG 3.0 publication and adoption by major customer-side procurement teams would change accessibility-question structure; (3) major vendor announcing a UX-specific certification or audit framework (UX equivalent of SOC 2) would warrant adding a certification question; (4) published independent benchmark of agentic AI vendors against UX assessment framework would harden or weaken the question set the existing playbook does not yet cover. Sibling /the-enterprise-agentic-ai-rfp-60-questions/ is primary playbook (38 citations); AM-167 covers procurement-clause instruments translating question-set output into contractually enforceable MSA terms; AM-181 covers strategic-narrative diligence checklist operating in parallel with RFP question set.
