Norman (2004)

“We are NOT all designers…a designer’s approach to creative problem solving is very different from how computer scientist, for

example solve puzzles.” - Bill Buxton(2007)

What I do know…• I can’t give you:

• 10,000 hrs of UX training (on top of your dev-tasks in 20 mins pres.)

• UX Training & Experience that helps ‘Predict’ User Intents, Reactions & Interactions

• Discern who can or can’t do ‘Design’• Know if your specific ‘Design’ will be ‘Effective’

• What I can give you:

• ‘Method’ to do ‘cheap & effective’ Usability Testing

• ‘Observe’ User Intents, Reactions & Interactions *Much Easier to Do*

• Provide an ‘Opportunities’ for team to act on ‘User Feedback’
