  • 33. Business analysis vs. usability
  • 34. Business analysis vs. usability
    • On a typical project:
      • What are a BA’s main goals?
      • What are a usability specialist’s main goals?
  • 35. 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*
  • 36. 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!
  • 37. 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.
  • 38. A better BA/usability result
    • Make use cases visual (where possible)
  • 39. A better BA/usability result
    • Leave the text for the details.
    • Not all visuals are clear!
  • 40. 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
  • 41. “ One way or another, you will be tested.” - Bruce Tognazzini
