The goal of this presentation is to give attendees a deeper understanding of usability testing so they can leverage it in their own work. The material will shed light on what is important to the research buyer and will help the research provider to better understand how to plan, moderate, and report on a usability study. It will also provide information on where they can go to learn more about this very practical qualitative method.
Kay will cover what a usability test is and when to use it, the key planning steps, the language around it, and the unique insights this method produces. She will also discuss the various approaches a market researcher can take when running a usability study at different points in a product’s development (e.g., concept, early prototype, released product).

What is a usability test?
• Qualitative study where typical users try to accomplish
typical tasks on their own with the product
• Point is to see how clearly the product “speaks” to
them, meets their expectations, fits into their typical
work and task flow
• Moderator & team watch participant working and keep
score of task success & failure, comments, body
language
5. 555
What can be usability tested?
• Web sites, software applications
• Consumer products (e.g., vacuum cleaners, ovens, mobile
phones – examples from projects I’ve done to illustrate the
range of where you can apply this technique)
• Packaging
• Customer service or ordering procedures
• Training & documentation
• Basically you can usability test any product or service
where there is user interaction
6. 666
Some Good reasons for running a
usability study
• Make interaction with a product as fluid & intuitive as possible
• Avoid embarrassment – expose usability problems
• Test design concepts
• Compare design approaches
• Challenge assumptions
• To compare your product with a competitor’s
• Improve ease of use and learning
• To better understand users
• To understand training and documentation needs
• To increase sales, improve your product’s reputation, decrease need for
technical support
• To save money and time (less need to rework the design, fewer calls to
customer support)
7. 777
Where does usability testing fit in with other
qualitative research methods?
• Similar to in-depth interviews, focus groups, and
ethnographies. Listen to participant, note their
body language, learn their work and task flow,
needs, attitudes, and perceptions
• Different from other forms of qualitative research
because goal is to watch participant perform tasks
against a product design and keep track of success
and failure

Major phases of a usability study
1. Planning the study
2. Running the study
3. Analyzing results
4. Reporting results
A typical soup-to-nuts usability study takes about 70 hours
12. 121212
Planning the study
• Determine study objectives
• Identify target user characteristics, write recruiting
screener, oversee participant recruiting & scheduling
• Create usability study plan and task list*
• Make sure prototypes & other stimuli are ready
• Manage logistics
*Bolded items are unique to usability testing
13. 131313
Usability objectives should focus on a
specific aspect of the product design
Aspects of an interactive product
design that affect usability
• Are the features, functions,
and content appropriate?
• Does the organization and
navigation align with the user’s
task and work flow, their
“mental model”?
• Do users understand labeling
& terminology?
• Do they know where to start,
what to do next, and the range
of available choices?
15. 151515
Sync testing approach to product’s
development stage
Test method Project stage Focus
Paper prototype Early Overall product concept,
terminology, navigation
Electronic prototype Design Task flow, visual design, page
layout, specific features,
validate redesign
Functioning product Development & QA Defaults, online help, feature
integration, performance
Comparison Post-release Product features, performance
benchmarks, can be within
your own product or against
competitor’s
16. 161616
Venue choices for a study
Venue Pros Cons
Facility Can invite lots of observers,
fewer logistical headaches,
can test wider range of
products
Artificial environment, costs more
Conference room Saves money - no travel, can
test wider range of products
More logistics, artificial environment,
observers want to sit in same room as
tester
Live online More natural (participant is
in their environment, saves
money, no travel, fewer
logistics, easy for team to
observe
Can only test Web-based products, hear
voice but don’t see body language,
need to recruit more tech savvy
participants, firewall issues
Native habitat (mobile studies) Person is in context of use -
people use mobile phones
when they are “on the go”,
cheap & quick
Cannot easily record, only have 1-2
observers
17. 171717
Tips on recruiting for a usability study
• Usability studies typically involve only a few participants (8-10)
• Choose confident and articulate participants who care about
the product category
• Aim to recruit people with varying levels of experience
• Define the required foundation skills
• Make sure participants understand what it means to be in
usability study
18. 181818
Task list development
EXAMPLE TASK LIST
“You are the owner of a family-owned business that has just deployed the
Acme Web Conferencing product. Today you are working from home but need
to hold several meetings with your managers and employees. For the first
time, you will be using your iPad to participate.”
• Task 1 – Your Administrative Assistant, Kathleen, has set up an Acme Web
conferencing meeting for you. Go to your e-mail and find the invitation.
• Task 2 - Join the conference.
• Task 3 – Enter your information: Chris Doe, DoeChris173@myemail.com,
987-123-9876.
• Task 4 - Enter the meeting room.
• Task 5 - Once you are in the meeting room, connect your phone to the Web
conference so you can hear what is going on.

Planning a study is very involved
Create project plans and check lists to keep your ducks in a row.
22. 222222
Running the study
Sessions follow a structure that is similar to any qualitative
research session:
• Moderate sessions – steps are the same
• Keep track of participants’ task success and failure
• Note comments, facial expressions, and body language
• Hold debrief discussions with participants and observers
• Administer surveys between tasks and after session has ended
During a usability study you are watching people’s behavior while
listening closely to what they say
23. 232323
What type of data do you collect?
• Collect objective results (can they do it? Define up front what
“success” means for each task)
• Emotional reactions
• Practical information (how does this product design fit into their
world? What kind of training would a person need to be
productive with this technology?)
• Typical measures (task success/failure, time on task)
• When they struggle, note why
• You see patterns after 3-4 sessions but new stuff always
emerges (depending on diversity of participant backgrounds)
25. 252525
Analyzing the study results
• Keep score of task success/failure by participant
and task
• Identify trends – What was easy? What was
hard? How did the product design play into these
results?
• Find verbatim comments and video clips that
encapsulate key findings
• Debrief continuously with clients – gaining
consensus on issues is critical to your success
28. 282828
Writing the report
• Use a conventional approach to structuring the report
(e.g., executive summary, methodology, findings)
• Group findings by product features and functions
• Where possible, tell the story with numbers (e.g.,
number of participants who succeeded at each task)
• Layer the information – place summarized information
in the report, and details in a spreadsheet
30. 303030
Look for opportunities to collect
quantitative data
Product Reaction Cards
Participants quickly select 5
attributed from among 118 choices
The attributes are balanced between
positive and negative
System Usability Scale
Participants answer 10 questions on
key aspects of usability
Survey produces a score between 0
and 100; a score <60 is considered
poor
31. 313131
Seek results that can be expressed in
pictures

Product Reaction Card results add
human interest
Text size indicates number of times that attribute was chosen
33. 333333

SUS scores < 60 indicate poor usability. See the study spreadsheet for details.
XYZ’s’ SUS scores from all
10 participants were
between 75 and 100
34. 343434
Reporting – each discipline expects
specific insights from the study results
Executives want a distilled version, an encapsulation of “the problems” and to
understand what is perceived as the premium this product offers
Product managers and marketing people seek insights on segmentation,
product identity, competitive information, participant reaction to feature sets
Product designers want detailed usability feedback to guide refinements to
the product’s interface and behavior. Is the design intuitive? How does it fit
into the user’s work and task flow?
Engineering needs to understand the usability bugs so they can prioritize
them and fix them (often their input is the bottom line)
Training and documentation people want to know which content to include in
their work

Hands-on exercise – usability test QRCA
VIEWS mobile app
STEPS
1. Translate the objectives into a task list
2. Break into groups of 2-3 people, one person is the administrator
another the participant, others are observers who will take notes
3. Run the study
4. Observers will record impressions on colored sticky notes (each
group will have its own color)
5. We’ll reconvene and do a mini affinity diagramming session to
tabulate and discuss the results and recommendations for
improvement. We’ll hold a debrief.
6. Kay present our results to Laurie and Eddie
7. Then we’ll pat ourselves on the back!!!
