Focus on those tasks you want users to perform On most e-commerce sites, that means buy something No point in optimizing peripheral areas of site

43 Planning a Usable Site Test and test again Many books/literature available on usability testing Dont fall into the touchy-feely trap Aesthetic preference is unarguable Do users accomplish tasks? Make errors? Meet objectives? Is the experience frustrating or not?

44 Managing a Usable Site Essential to have a feedback loop How do users perform? Can they do what they want? Do they do what you want? Best feedback is combination of voluntary and involuntary Ask for feedback and make it easy to provide Track user behavior
