✤ Where it may be risky to go minimalist
✤ How to think about the trade-offs
✤ What’s essential
✤ What might be nice to have

Improvise: Ground rules
✤ Say “yes.”
✤ Trust your team and your participants
✤ Don’t let the team or stakeholders block
✤ Work to the top of your collective intelligence
27. 27
How we got value
✤ Used the ballots and instructions at hand
✤ Focused on one thing at a time
✤ Had participants generate and collect data
✤ Drafted observers and debriefed

Where’s the value in testing?
70% watching someone use
the design
20% working with the team
to prepare to test
8% discussing what
happened
41. 41
Getting value in the wild
✤ Use what’s at hand
✤ Narrow the scope of the test
✤ Focus on
✤ what can make the most difference to the
most users
✤ what can be implemented easily with the
resources available
42. 42
✤ If you need
✤ summative
data
When is testing in the ✤ benchmarks
✤ answers to
wild not valuable? hard
problems
47. 47
What do you need?
✤ To inform a design:
Testing in the wild Classic usability testing
Qualitative data Quantitative data
Opportunity Planning
Fits the schedule Don’t know how to fit UT into
the schedule
Just in time After the fact
$ $$$$
Something Maybe nothing
48. 48
Where’s the ROI?
✤ Qualitative data
✤ Opportunity
✤ Fitting into a schedule
✤ Timeliness
49. 49
So far.
You don’t have to do it Value of usability Tradeoff: having
by the book testing some data over
having no data
+ observing users
+ working with the
team

Coming up.
What’s the bare Steps for testing in What to add if you
minimum the wild have resources
52. 52
What you need
Somebody
(Human)
✤ Someone who will try the design
Something Some place
✤ Somewhere to test (Activity) (Context)
✤ Something to study
53. 53
1. Plan, minimally
2. Get the team on
board
3. Design the test,
minimally
4. Recruit
participants
5. Conduct
sessions
Follow these steps: 6. Debrief and
decide
55. 55
Plan, minimally: Example
✤ What: near-final design
✤ Why: inform user training and support
✤ Who: inexperienced customers
✤ When: the end of the week
✤ Where: trade show at user group meeting
56. 56
Minimalist plan
Find out whether information about admission is
Goals and objectives
easy to find and use
Participant
People who have college-bound kids
characteristics
Description of Sit-by parents attending a high school basketball game, each
method trying three university sites with the same scavenger hunt task
Find out how and when applications are due
List of tasks Determine whether there are fees for applying
Learn when acceptances will be sent
57. 57
Get the team
on board
✤ Visualize the desired user
experience
✤ Share the intellectual property of
observing users
58. 58
Design the
test, minimally
✤ Why are you testing?
✤ What questions are you trying to
answer?
✤ What constrains the design?
✤ What are you going to do with
what you find out?
60. 60
✤ Staff not on the
design project
✤ Friends and family
✤ Personal,
professional
networks
✤ Online social
networks
✤ Community
organizations
✤ Online classifieds
✤ Association,
society, user
group, union
Sources of participants contacts
✤ Temp agencies
61. 61
Conduct
sessions
✤ Rehearse (P1)
✤ Interview-based tasks (or based
on previous field work)
✤ Explore in short, focused
sessions
✤ Iterate test design and product
design
62. 62
Greet the
participant
Explain the study,
your role, and their
role
Interview (maybe)
Do tasks from
interview
Debrief with
participant
Session outline Debrief with
observers
63. 63
✤ Impartial,
unbiased
observing
✤ No teaching!
✤ Listen and
watch
✤ Ask open-
ended
questions:
Moderating, not training Why? How?
What?
64. 64
Debrief and
decide
✤ Write up issues on sticky notes
and sort them into priority lists
✤ Ask for top 10 items -- base on
data and observations, not
opinion
✤ Take a vote for priorities
66. 66
✤ Screened,
scheduled
participants
✤ Official
paperwork
Add these ingredients
✤ Recordings
✤ More observers
67. 67
Participants
What Why
appropriate experience greater confidence in data
scheduled ahead of time easier to get data
68. 68
Paperwork
What Why
script ensure consistent instructions and moderating
consent forms official acknowledgment for taking part
recording waivers permission for recordings
pre-test questionnaire experience, knowledge, value
post-test questionnaire feedback on tasks, UI
69. 69
Recordings
What Why
audio transcripts, verbal protocol analysis
video or photos stories, double-check, highlights
Morae, Camtasia, other digital data, automated collection
73. 73
Quick. Cheap. Insightful.
You can compensate Low risk, little money Value comes from
for some getting as close as
shortcomings, and just possible to what real
test more people are doing
with your design
