Westminster Hub, London UK 22 January 2014
===
Who is it for?
This workshop is for those who want to create products that will be easy to use. Usability testing is an important part of the process of designing digital products, but it can often be overlooked due to time, money, and training constraints. In this workshop you'll learn how to test any product's usability without spending a large amount of time and money. And how to use what you've learned to improve the product.
Who is it taught by?
This workshop is being taught by Evgenia Grinblo @grinblo, User Experience Specialist at mobile agency, Future Workshops. Born in Siberia, Jenny freelanced and trained in ethnographic research in Israel and the USA, before bringing her talent to the UK. Her pet peeve is badly written error-messages and she has a growing collection of them. You'll find her speaking on empathy, UX, and other passions.
What you'll learn
An introduction to usability testing - what is it?
Who should you test your product on?
What do you test?
How to facilitate a test and get reliable results
How to manage data and act on your findings with your team
Tools: Cheap, quick and effective testing tools for mobile and the web.

cumbersome the users experience with the

... What the usability testing did for me was
really prove how much tech people can
lose sight of who they are building
for. It about going back to basics in some
cases.

36. PREPARING A TEST PLAN
To run a test, you need
ā£
Some representation of your product
ā£
Preferably interactive
ā£
Doesnāt have to be ļ¬nished
ā£
Or: competitor product!
ā£
Idea of what you want to test
37. PREPARING A TEST PLAN
What do we test?
ā£
General impressions
ā£
Ease of use of critical features
ā£
Features weāre not sure about (e.g., is the
help clear?)
ā£
Response to design, iconography
Tip: start from high-level when testing
prototypes, test the details with later builds

47. EXERCISE 1
Choose a product to test
Time: 10 minutes
ā£
We are going to validate an existing,
ļ¬nished product
ā£
As a group, decide on a website or app to
test
ā£
It can be your app - I must be able to
interact with it
Tip: avoid sites that require logging in (unless
you have a login to share)
49. PREPARING A TEST PLAN

ā£
Any details like login information, etc
53. PREPARING A TEST PLAN
Scenario Tips
ā£
Avoid using terminology from the
interface (e.g., search, tag, ļ¬lter)
ā£
Scenarios can have steps (e.g., ļ¬nd a
recipe and add it to your collection)
ā£
Escalate the diļ¬culty as the test
progresses
54. EXERCISE 2

57. FACILITATING A TEST & RECORDING RESULTS
Facilitating
ā£
Practice staying quiet
ā£
Remind the participant to speak out loud
ā£
Donāt give anything away
ā£
Be reassuring, say thank you
ā£
If they get stuck, wait (a little)
58. FACILITATING A TEST & RECORDING RESULTS
Facilitator Cheat-Sheet
If they forget to think aloud
ā£
"What are you thinking right now?"
ā£
"What are you finding confusing on this
screen?"
ā£
"I know it's an unusual thing to do but could I
please ask you to keep thinking out loud and
talk as you go along? It really helps me
understand your experience better."
59. FACILITATING A TEST & RECORDING RESULTS
Facilitator Cheat-Sheet
If they get stuck
ā£
"This is very helpful for us, we are uncovering
a lot of problems in the design that will help us
make the app better."
ā£
"I can already see how useful this is going to
be in improving the app."
60. FACILITATING A TEST & RECORDING RESULTS
Facilitator Cheat-Sheet
If they have a question
ā£
"Please continue in the way that makes sense
to you. We will learn a lot from seeing how
you proceed with this without any help."
ā£
"I will be happy to answer your questions at
the end. Please try to try this task for a bit
longer."
61. FACILITATING A TEST & RECORDING RESULTS
Facilitator Cheat-Sheet
The golden go-to
ā£
"We expected to uncover problems in the
design. You are not doing anything
wrong - we knew there would be issues and
you are helping us find them."
62. FACILITATING A TEST & RECORDING RESULTS
People will feel stupid.
Make them feel at ease.

63. FACILITATING A TEST & RECORDING RESULTS
Ways to record our ļ¬ndings
From easy to complicated
ā£
Pair up with a note-taker
ā£
DIY recording equipment
ā£
Professional recording equipment
ā£
Live-stream to a group of stakeholders
64. FACILITATING A TEST & RECORDING RESULTS
Note-taking brings down 2
barriers to testing: time &
equipment
(But Iāll give you some tips on recording later!)
64
65. FACILITATING A TEST & RECORDING RESULTS
Note-taking tips
Only record whatās important
ā£
If someone is really happy
ā£
If someone is really frustrated
ā£
If someone fails a task
ā£
Write down short quotes if you can
66. FACILITATING A TEST & RECORDING RESULTS
Notes Example
ā¢
Taps Map on merchant profile but this opens the system Maps
app ā confused
!
ā¢
Goes to Search and types ācoffee shopsā but there are no results
ā āwhy canāt I see whatās around me?ā
!
ā¢
"If I had to think about something around me, Iād start the
merchant profile and expect to see other things around me"
!
ā¢
The icons arenāt telling me that Cafe Nero is a coffee shop

67. FACILITATING A TEST & RECORDING RESULTS
What to bring to the test
Printed scenarios & tasks for participant
Printed scenarios & tasks with success paths for
facilitator
Facilitator script
Optional: List of pre-test and debrief questions
Consent form (if needed)
Pen + paper / recording tools
Test setup checklist
68. FACILITATING A TEST & RECORDING RESULTS

Prepare participant forms: scenarios,
intro script, consent form
Optional: Verify the recording equipment
Optional: Make sure the brightness on

69. EXERCISE 3
Usability Test
Time: 40 minutes
ā£
Every 8 minutes, swap one member of
your group in exchange for a member
from another group
ā£
The āforeignā member is the participant
ā£
Start running through the test youāve

73. ANALYSING & PRESENTING FINDINGS
What to do with all the data?
ā£
Identify changes with the biggest impact
& smallest eļ¬ort as a team
ā£
Find the ālow-hanging fruitā
ā£
What has impact on the bottom line?
ā£
Put everything else in the ice-box
74. ANALYSING & PRESENTING FINDINGS
Identifying key ļ¬ndings
High-priority: people fail, or abandon the
task
Medium: people succeed but are
frustrated and unhappy
Low: people would enjoy the app more if...
Tip: Work hard to prioritise the
highest-impact items. You canāt ļ¬x
everything.
76. ANALYSING & PRESENTING FINDINGS
Presenting ļ¬ndings

77. EXERCISE 4
Identifying Key Findings
Time: 15 mins
ā£
As a group, debrief on each personās notes
ā£
Find 2 high, 2 medium, and 2 low-priority
usability problems
ā£
What will you ļ¬x ļ¬rst? Why?
ā£
Jot down a quick summary of key ļ¬ndings
to present to the larger group
79. SUMMARY & CONCLUSION
Summary
ā£
Match your test artifact to your scope
ā£
Plan realistic scenarios that donāt give
away the test purpose
ā£
Be encouraging and open to feedback
ā£
Record only whatās needed
ā£
Prioritise ļ¬ndings for maximum
impact
81. SUMMARY & CONCLUSION
Usability is only one part
Building a product isnāt just about usability:
ā£
Business goals
ā£
Usefulness & desirability
ā£
Diļ¬erentiation
ā£
Vision of the future
ā¦ But itās a great start!
82. SUMMARY & CONCLUSION
Usability is only one part
Create a vision of
our oļ¬ering to
people
Match the vision
with real-world
behavior
Translate user
research into user
tasks
Create interfaces
to support that
journey
Plan the journey
to accomplish
each task
Iterate and
simplify those
interfaces
Test how real
people use our
interfaces
