  • 23. Business analysis vs. usability
  • 24. Business analysis vs. usability • On a typical project: – What are a BA’s main goals? – What are a usability specialist’s main goals?
  • 25. 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*
  • 26. 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!
  • 27. 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.
  • 28. A better BA/usability result • Make use cases visual (where possible)
  • 29. A better BA/usability result • Leave the text for the details. • Not all visuals are clear!
  • 30. 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
  • 31. “One way or another, you will be tested.” - Bruce Tognazzini
