Frustrated Users!

The importance of User Testing
Changes after launch are expensive!

When to test...
• Preferably as early as possible
• ‘1 designer, 1 user, 1 hour, every week’
• 1 User test is 100% more then no tests at all!

What to test...
• Ideas (for example: brainstorm results)
• Sketches (layout)
• Wireframe(s) (functional design)
• Graphical Design (look & feel)
• Mock-ups/prototypes
• Test-cases

How to test...
• Talk to your end-users!
• Paper Prototyping
• Assignment testing
• Remote testing
• Eye Tracking
• Expert-review

Talk to your end-users!
Sit down with a person or a group of persons who represent
the end-users of your product and brainstorm with them about
their wishes, needs and other experiences...
