Transcript of What's the difference between user experience and usability?

Keith Kmett, CUA What's the difference between
user experience and usability? Two uses of the term Defining Usability Defining UX Learnability : How easy is it for users to accomplish basic tasks the first time they encounter the design?

Efficiency : Once users have learned the design, how quickly can they perform tasks?

Memorability : When users return to the design after a period of not using it, how easily can they reestablish proficiency?

Errors : How many errors do users make, how severe are these errors, and how easily can they recover from the errors?

Satisfaction : How pleasant is it to use the design? The problem Because UX and usability disciplines care about user satisfaction, a lot of people use the terms synonymously.

But the fact remains that, even though they are closely related, UX and usability are different. Possible answer Finding a UX professional How do you know if someone that talks about UX a lot is qualified to be a UX designer?

Do they know usability principles?

Is their portfolio a list of URLs or case studies?

Can they critique on their feet?

Are they effective communicators? Any questions? Thank you! @kkmett

Because UX is still gaining popularity in businesses, your candidate has to be exceptional at presentations and communicating design principles.
