Q

User-Centered Design

A
  • Product development often leaves out UX
    • Just it works and looks good doesnt mean it has a great UX!

Q

User Experience

A

How a product behaves and is used in the real world, incorporating a range of factors.

Users need products that:

  • work
  • are usuable
  • meet expectations

Different user expectation, whether wanting to read information (e.g. news), or manipulate information (web application).

Important because people rarely read web pages word by word; instead, scane, bounce, jump… for about 10 seconds per page.

UX should be useful, desirable, usable, accessible, credible, findable
