How to do rapid prototyping and user testing in a user centred design process.

1. Discover problems
early on

2. Agenda

5. UCD - User Centred Design

6. „The central premise of user centred
design is that the best designed products
and services result from understanding the
needs of the people who will use them.“
Design Council

7. UCD - User Centred Design
INTERACTION DESIGN

8. Requirements Engineering
Understand the user and the environment
• Interviews (Stakeholders & Users)
• Contextual Inquiry
(observe the user in the environment)
• Consolidation of the findings
• Modelling of Personas and Scenarios

10. Concept
Brainstorm and scribble
• Goal of iteration
• Which requirements to evaluate
• Define information architecture
• Scribble interaction concepts

11. Prototyping
Simulate the user experience
• Develop prototype
• LoFi to HiFi
• Paper prototype
• Interactive prototype

12. Evaluation
Test the prototype
• Write test scripts
• Recruit test users
• Conduct user test
• Analyze results
• Plan next iteration

13. Implementation
Build a solid interaction concept
• Finetune visual design
• Handover to engineering
• Observe implementation
• Launch

14. Prototyping
LoFi to HiFi

18. User Testing
Test prototype with users

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

20. Hallway Testing (LoFi)

21. In-House User Test (LoFi/HiFi)

22. Remote User Test (HiFi)

23. Usability Lab (HiFi)

24. Recruit Test Users
Find people fitting the personas

25. Recruiting
• Use In-House user database
• Use Facebook or Craigslist Ads
• Order from market research company

26. Recruiting Challenges
• Time consuming and expensive
• Unreliable testers (no shows)
• Always ending up with same people (or friends)

29. Conduct Users Test
Discover problems early on

30. 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

33. Do you think, you will try any
of this in the future?

34. Thanks for testing!
