  • 11. 10 Most Common Misconceptions About User Experience Design
  • 12. 1 User experience design is NOT User interface design “User experience isnt a layer or component of a product or service. Its really about the design of whole systems and their interconnections.”Andrew Hinton, Senior information architect atVanguard
  • 13. 2 User experience design is NOT A step in the process “User experience design isnt a checkbox. You dont do it and then move on. It needs to be integrated into everything you do. Its a process of continually learning about users.”Liz Danzico Chair, MFA in Interaction Design, School ofVisual Arts in NYC
  • 14. 3 User experience design is NOT Just about Technology “User experience design is not limited to the confines of the computer. It doesnt even need a screen... User experience is any interaction with any product, any artifact, any system.”Bill DeRouchey, Director of interaction design at Ziba Design
  • 15. 4 User experience design is NOT Just about Usability “While usability is important, its focus on efficiency and effectiveness seems to blur the other important factors in UX, which include learnability and visceral and behavioral emotional responses to the products and services we use.”David Malouf, Professor of interaction design, Savannah College of Art & Design
