Guerilla UX techniques

  1. 1. Chris Bush UX Practice Lead @wearesigma / @suthen
  2. 2. Taking your research further A bit about Sigma (our services and clients) Why talk about guerrilla testing? Getting started with guerrilla testing Wrap up
  3. 3.  User Research & Testing  Interface & Interaction Design  Web, Mobile & Application Development  Enterprise Content Management  Training & Support
  4. 4. Expensive - no budget Time / Resource consuming - delays development Not a primary concern - Focus on traffic acquisition
  5. 5. Pros: • Users are often in a more informal environment (comfortable and relaxed) • Great for bringing in teams together to observe users (and discuss) • Help and support when defining tasks and scenarios • Less likely to introduce moderator bias • Detailed external provider analysis and reports • More likely to use advanced data collection (Eye tracking) Cons: • Can be costly • Less likely to want to invest in early stage testing (Prototypes and early beta code) • Less likely to perform iterative tests
  6. 6. Pros: • No specialist equipment - only low cost software • Very portable (on location, café, office, home) • Great for early stage testing (Prototypes, etc.) • Great for Rapid Iterative Testing and Evaluation (RITE) • Minimal overhead (Time, People, Cost) • Great for etsablishing organisational buy-in Cons: • Moderator or reviewer bias • The team takes on responsibility for ensuring everything is organised (Users, Room, Tasks, Write up) • Finding a good testing room is sometimes tricky
  7. 7. • Any users are better than none but aim for two rounds: 5-10 per round • Aim for a good cross-section of representative users • Be aware of the peril of coffee shop testing… • Max 30-45 minutes to complete (around 5 tasks) • Create meaningful tasks – word tasks as scenarios * • Think aloud and retrospective think aloud • Discussion guide – consistency is important • Rotate tasks (ABC / BCA / CAB) to remove bias • Use a scribe *
  8. 8. • Don’t be too specific “Find and fill in the customer returns form.” • Allow users the opportunity to decide what the most suitable solution is to the same problem “After receiving your new camera you have noticed the lens is cracked. Using the site can you request a replacement.“ • Be pragmatic about leading questions • But, always do a control test. (you’re testing your questions and the software at this point)
  9. 9. • Use the most comfortable room you can find • Sit back from the user • Use reflective questions • Don’t be a monster! • If the user is struggling help them
  10. 10. Sit back from the participant Screen projection can be useful Scribe sits away from the main study
  11. 11. • A second set of eyes helps to remove any bias • It can save you hours of review time • Define a coding system to help identify themes when taking notes • .N – Navigation • .S – Search • .C – Content / Information • .D – Design • .T – Trust and credibility • Use a text expander and time code your notes • Spend 30mins after each session doing light analysis.
  12. 12. Use a text expander
  13. 13. Input devices Touch Pointing devices

  15. 15. Interviews Surveys User testing Remote User testing
  16. 16. Interviews Surveys User testing Remote User testing
  17. 17. • Always aim to test on five to ten people and for best results run two iterations of your tests • Test your questions on real people before you do your test. They nearly always need refinement • Take time to set up your room to make it as comfortable as possible. • Remember to sit back from the user so they don’t feel like they are being watched too closely. • Use reflective questioning. Participant: “Why did that happen when I clicked there?” You: “Why do you think that happened?”
  18. 18. • Use a scribe to ensure you get the most out of the session. It also helps remove any moderator bias. • Code your notes as you go to save you time in analysis. (-n for navigation issues, -f for form issues, etc.) • Take 15mins after each session to review the analysis and categorise the results. Do not try to solution new ideas at this point, if you’re not careful you could end up distorting the results of following studies. • Lastly, If your project requires impartial validation consider using an agency and lab
