    • Business analysis vs. usability
    • Business analysis vs. usability
      • On a typical project:
        • What are a BA’s main goals?
        • What are a usability specialist’s main goals?
    • Business analysis vs. usability
      • Typical BA goals (from a UX perspective :)
      • Meet business goals by:
        • Researching current processes
        • Identifying what the new system should do (requirements)
        • Designing improved processes
      • Typical UX goals
      • Meet business and user goals by:
        • Researching users
        • Identifying how the new system should work (design principles)
        • Designing a UI with the users in mind
        • Evaluating/iterating the design until it works well*
    • A better BA/usability result
      • Beware the ivory tower
        • Secondhand folklore instead of user research
        • Opinion-centered design*
        • Long cycles with little user involvement
        • Different ≠ better
        • WE ARE NOT THE USER!
    • A better BA/usability result
      • Develop use cases and UI in parallel
        • BA, SME: Do skeleton draft of UC.
        • BA, UX: Talk through the main points.
        • UX: Sketch some screen variations.
        • BA, SME: Start filling in the details.
        • BA, UX, SME: Iterate/refine UC and UI
      • UI design often improves the UC itself.
    • A better BA/usability result
      • Make use cases visual (where possible)
    • A better BA/usability result
      • Leave the text for the details.
      • Not all visuals are clear!
    • A better BA/usability result
      • Make the UI a visual companion to the UC
      • Signing off a use case without a UI = writing a bad cheque
    • “ One way or another, you will be tested.” - Bruce Tognazzini
