The User Experience Design blog reports that Jonathan Hassell of BBC online shared a presentation on the challenges and methodologies of the company’s Usability & Accessibility team.

The short presentation describes the challenges, such as a wide range of platforms and audience types, as well as the wide-range of research tools that are used to understand and address them, from card sorting to ethnographic research.

The video of the presentation is also available (requires registration, go to “Web 2.0, Social Networking, Usability, Design & Build Theatre,” then “Wednesday at 13:00″).
