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.”
