Running user testing

  1. 1. Strategy Research Design Delivery Running user testing Steve Cable (@steve_cable) Walt Buchan (@silverfoxyboy) Thursday, 25 November 2010
  2. 2. 2 Why user test Pain points identified from analyticsReported problems Strategic changes People test their website for different reasons Thursday, 25 November 2010
  3. 3. 3 What stage in the design process should you test? HTMLDesignsWireframesSketches The earlier you begin testing the better. Test as many stages of the design as the budget allows There are issues that testing designs will bring up that wireframes won’t, and issues that testing HTML will bring up that designs won’t Thursday, 25 November 2010
  4. 4. 4 Recruitment Getting the right people is vital the type of recruits usually come from user groups already defined by the client We like to define user groups by the tasks they will perform on the site/software for a shopping site it could be split between people who shop for themselves, and people who shop for others Usually its a good idea to get a mix of existing and new users We avoid ‘Expert’ users as these people usually only represent a small portion of your user group Thursday, 25 November 2010
  5. 5. 5 The test plan We produce a test plan in collaboration with our client It defines the overall objectives of the test and what we want to find out on each part of the website However we don’t use it as a rigid script. We use it as a guide This means if we find an interesting new line of investigation during a test, we can explore it Thursday, 25 November 2010
  6. 6. 6 Who should be involved? Thursday, 25 November 2010
  7. 7. 7 Users 6 participants plus 1 The tests are qualitative research, meaning we are not trying to prove something, just identify issues we find six participants are enough to identify the majority of issues The extra user is paid to be around all day incase one of the 6 participants does not show up it means we can avoid the embarrassing situation of a no-show Thursday, 25 November 2010
  8. 8. 8 Moderators That’s us! We use two moderators for our tests One moderator can concentrate on the interview The other can concentrate on the note taking (And looking after the clients) This means we can do more in depth interviews and have more comprehensive notes to work from afterwards Thursday, 25 November 2010
  9. 9. 9 Stakeholders We always encouraged Clients, developers, designers and anybody who’s involved to come and watch the tests This is so stakeholders can see any issues users are having for themselves It’s much more convincing than having a consultant telling them about it a week later Thursday, 25 November 2010
  10. 10. 10 The test Thursday, 25 November 2010
  11. 11. 11 What devices or media can be tested Mobile devices e.g. Phones, Media players, Tablets Personal computers e.g. PCs, Apple Macs Printed material e.g. Brochures, Printed forms Prototypes e.g. Paper based, magnetic stickers We’ve tested all of these devices and materials for a number of different clients Thursday, 25 November 2010
  12. 12. 12 Test structure Preamble Usability test Summary & Close Depth interview Usability test Summary & Close Test focussing on usability Test focussing on user experience Examples of additional user testing • Benchmarking exercises • Simple card sorting and ranking exercises • Preferences e.g. Photography styles, Tone of Voice, Visual style This structure focuses on finding specific usability issues This structure focuses on the wider context of use Great for producing mental models and user journeys Tests can be structured in different ways to achieve different results Thursday, 25 November 2010
  13. 13. 13 Interview techniques • Put the participant at ease ‘It’s not you being tested, it’s the website’ • Probe where necessary, leave space for the participant to think • Listen, show interest, (Be consistently interested or the participant will learn what you want to find out) • Don’t lead the participant, be careful with words and body language • Use open questions: Who, What, When, How, Where, Why • It’s about what they actually do, not what they might do (or what their mum would do) There are loads of interview techniques, but these are the six we feel are the most important to remember Thursday, 25 November 2010
  14. 14. 14 The set up Thursday, 25 November 2010
  15. 15. 15 Why no two way mirror? Big mirrors can make participants feel uneasy Most people only know them from police interrogations in films Anybody watching has to be silent in the dark It can be hard for anybody to stay alert after four hours of testing in these conditions Thursday, 25 November 2010
  16. 16. 16 The set up Instead we use video link up This makes the interview room seem a little more private It also means the people watching can make as much noise as they like It also gives them a better view of whats going on as they can see: • A direct feed from the users computer (With live eyetracking data • A shot of the users face • A shot of the computer screen (For when the user points at something) Thursday, 25 November 2010
  17. 17. 17 The output Thursday, 25 November 2010
  18. 18. 18 Eye tracking data Heatmaps show an aggregated view of what all the participants looked at on a page It’s great for backing up what we have identified as issues This example shows how all the users were missing important information on the right of the page Thursday, 25 November 2010
  19. 19. 19 User videos We produce full length videos of the user tests for the clients to keep We also produce highlight clips to highlight particular problems that were identified Thursday, 25 November 2010
  20. 20. 20 Recommendation report Our reports are designed to be easy to use Very visual with one clear concise point per page We back up each point with a quote from the participants We don’t just highlight problems. We also provide clear actionable recommendations These recommendations are prioritise with the client to provide them with a clear direction for improving their site Thursday, 25 November 2010
