What‟s involved in a usabilitytest• Participants performing meaningful tasks• Real users – not your BFF• Observers (you or design team)• Recording data for analysis
You can test ANYTHING• Hand-drawn sketch• Wireframe• Screenshot / JPG• HTML prototype• Live site• Competitor‟s site!
Why care about usability?• Simple errors can lead to big problems• If the customer isn‟t happy, nobody‟s happy.• If visitors can‟t easily access your info, why have a site at all?• Casual visitors have a different experience than those who work with a website every day.
