– Experience level and knowledge

– Technology

Interview to Discover/Confirm…

Styles of Interviews

19


• Memory tool for facilitator

Find A Partner


• Do you regularly book your travel online to save

money?

Question 1: What is a better question?

24


• How often do you travel?

– <listen>

• What proportion of that do you book online?

– <listen>

• Why do you book travel online?

– <listen>

Alternates – Question 1

25


• Address one issue at a time and avoid double-

barreled questions.

Rationale - Question 1

26


• What are your thoughts about a new feature, that

allows you to instant message a travel agent with

any questions, as you book your travel?

Question 2: What is a better question?

27


• Would you like to correspond with a travel agent

while you are booking travel?

– <listen>

• What are some ways that you would like to

correspond with a travel agent while you are

booking travel?

– <listen>

Alternates – Question 2

28


• People are not good at predicting the future.

• Can only tell you what they’ve done in the past

– you can assume they will repeat

– job interviews - behavioral questions

Rationale – Question 2

29


• Remain passive (body, face)

• Don’t confirm or reject answers

• Listen for vocalizations

• Watch non-verbal gestures

– Encourage participant to elaborate

• Ask your question and let them talk

Card Sorting


• Maximize probability of users finding content

• Explore how people are likely to group items

• Identify content likely to be:

– Difficult to categorize

– Difficult to find

– Misunderstood

Card Sorting

Users organize information

• Easy and inexpensive

• Use to determine:

– Order of information

– Relationships between info

– Labels for navigation

– Verify correct audience

Benefits of Card Sorting

35

Gaffney, Gerry. (2000) What is Card Sorting? Usability Techniques Series, Information & Design.



36

Open or Closed (Reverse) Sort?

? ? ? Group

1

Group

2

Group

3


• One title/subject on each card

• Short for quick reading

• Detailed enough to understand

• Supplement - short description on back

• Use printed stickers (handwriting)

• Practice session first

Card Basics

37

Preventive Care

Guidelines

36


• Representative of users

• Minimum of 6

• More participants = more data to analyze

• Allow one hour for 50 items

• 30 – 100 cards

Participants

38


• Shuffle cards

• Ask to:

– Group items in own way

– Talk out loud

• Think about:

– What expect to be together

– When expect to see

Facilitation/Direction

39


• Card doesn’t fit: make separate group

• Not relevant: tell me

• More than one place: tell me and put in best fit

• Items not understood

– Correct audience?

• Items without consensus

– Re-name item?

– Include in more than one category?

Issues

40


• Ask to

– Describe groups and name them

– Describe overall rationale for grouping cards

– Show best example from groups

– What was difficult? What was easy?

– Happy with final outcome?

Grouping Cards

41


• Codes on cards = faster data analysis

• Standardize group names

• Look for patterns

• Excel Spreadsheet (Donna Spencer)

• Online tools - limited analysis

Analysis

42


• Moderated

• Un-moderated

Online Tools

Usability Testing


Usability Testing

• Measures users ability to achieve specific goals

of effectiveness, efficiency, and satisfaction.

• Real users,

doing real tasks

• Prototypes or live products

• Observed, not guided


Can Test…

• Websites, mobile apps, blenders, airport service

• Simulations or mockups

• Early prototypes (paper, low-fi)

• Production prototypes (html, hi-fi)

• Help documentation

• Processes (receipt of materials, purchase)


It is not…

• Quality testing

• Full accessibility testing

• System testing

• Acceptance testing


Don’t need a lab, but it is nice

• Anywhere

• Any Stage

• Anytime

Participant

observed through

2 way mirror and

on screens


Just Do It!

• Anywhere (conference room, remotely)

• Any Stage (earlier in process the better)

• Anytime (un-moderated)

• Realistic test environment

Prototype Testing

• Find out if initial designs are helpful

• Before money spent on visual design

or backend development


Avoid mistakes

A/B Testing

• Answer questions about:

– Layout on homepage

– Effectiveness of banners

– Choice of wording on call to action

Current Site/App Testing

• When redesign is planned

• Identify and clarify existing issues

– See drop off on analytics – Why?

• Usability heuristics being achieved?

– System status available

– Recognition, Not Recall


Regular Testing

(Yes, this is an old idea; a great one!)


• Make team aware

• Invite everyone

– Watch remotely

– Recurring meeting invites for stakeholders

User Testing Day!


“Teams should stretch

to get work into that day’s

test and use the cadence

to drive productivity.”

- Jeff Gothelf

Tweak, Don’t Redesign

• Small iterative changes

– Make it better now

– Don’t break something else

• Take something away

– Reduce distractions

– Don’t add – question it

Rocket Surgery Made Easy: The Do-It-Yourself Guide to Finding

and Fixing Usability Problems. By Steve Krug


True Statements

• All interfaces have usability problems

• Limited resources to fix them

• More problems than resources

• Less serious problems distract

• Intense focus on fixing most serious

problems first

Adapted from: Rocket Surgery Made Easy: The Do-It-Yourself Guide to Finding



Goal

• Identify top 5 or 10 most serious issues

– Top 3 from each list

– Prioritize from lists

– Commit resources for next sprint

– Stop

is building something

no one wants“
