UX cognitive validation checklist by audience and device

Purpose

Compact checklist to validate portal experience clarity, usability, and safety for non-technical and technical audiences across local-first and staging.

1. Baseline criteria (for all audiences)

  • plain language, no unnecessary jargon.
  • next action visible in under 5 seconds.
  • always show response origin when applicable (source/citation).
  • error messages include guided recovery.
  • high/critical risk decisions must expose explicit HILT gate.

2. Audience validation matrix

Audience UX objective Minimum criteria Evidence
Citizens complete informational task without support clear CTA, short text, visible source, stable mobile route screenshots, task time, drop-off rate

3. Validation by HMI device

Device Minimum checks
Smartphone one-hand navigation, readable text, short scroll, stable login
Tablet table readability, top-level primary actions, fast feedback
Laptop/PC full panel, filters, downloadable evidence, role-based access
CLI/Bastion command narrative, explicit risk, human-readable output 
python3 scripts/verify/citizen_hmi_ux_guard.py
python3 scripts/verify/citizen_role_routing_contract_guard.py
python3 scripts/verify/stakeholder_mobile_mvp_ga_guard.py
bash scripts/proxmox/local_uat_battery.sh --env-file env.dev.local

5. Human validation closure

  1. register findings by audience in issue or PR.
  2. set final status: approved, changes requested, or blocked.
  3. if risk is high/critical, attach explicit HILT decision.
  4. only promote to HOSTPROXMOX after valid local-first evidence.
