The challenge

Within the ENTi initiative, the goal was to evaluate the real user experience, including users with accessibility needs, to identify usability and accessibility barriers affecting navigation, comprehension, and execution of key tasks on the portal. The objective was to detect structural, cognitive, and interaction issues, ensuring a more inclusive, clear, and efficient digital service.

Key activities

  • Recruitment and moderated testing with 7 users (including users with accessibility needs)
  • Accessibility barrier assessment based on WCAG and UX best practices
  • Testing of critical tasks (search, navigation, understanding, and completion of key actions)
  • Measurement of average time to identify key information during task execution
  • Behavioral observation and qualitative analysis of friction and errors
  • Usability perception measurement (SUS) and identification of failure patterns
  • Insight synthesis and prioritization of improvement recommendations

The recruitment phase

Great usability insights start with the right people in the room. Recruiting participants for usability and accessibility testing isn’t just a checkbox—it’s how we make sure we’re designing for real experiences, not assumptions. 

By bringing together users with different needs, abilities, and contexts (including those who rely on assistive technologies), we uncover the moments that truly matter—the friction, the surprises, and the opportunities to do better.
