Scenarios

• Goal of iteration• Which requirements to evaluate• Define information architecture• Scribble interaction concepts

PrototypingSimulate the user experience

• Develop prototype• LoFi to HiFi• Paper prototype• Interactive prototype

EvaluationTest the prototype

• Write test scripts• Recruit test users• Conduct user test• Analyze results• Plan next iteration

ImplementationBuild a solid interaction concept

• Finetune visual design• Handover to engineering• Observe implementation• Launch

PrototypingLoFi to HiFi

User TestingTest prototype with users

Testing methods

• Hallway Testing • Expert Review• In-House User Test• Remote User Test• Usability Lab

Conduct Users TestDiscover problems early on

Best practices

• Do a dry run test• Mention that prototype and not user is tested• Ask test user to think aloud• Only one person moderates• Another person takes notes• Don‘t be suggestive• Follow up question for everyone
