5Contextual Design
- Hugh Beyer
- Karen Holtzblatt
6Contextual Design Concepts
- Contextual Inquiry
- Work Models
- Interpretation Session
- Affinity Diagram
- Consolidation of Work Models
- Work Redesign
- User Environment Design
- Mock up and test with users
7Basic Principles
- Go where the user works
- Observe the user as he works
- Talk to the user about the work
8Models for Interaction
- Scientist / subject model
- Parent / child model
- Teacher / student model
- Master / apprentice model
- (Rather, apprentice / master model)
- Relationship models have two sides
- Playing one side drags the opposite person into
the other side
9Sutras of Contextual Inquiry
- Master apprentice model
10Master Apprentice Model
- When you are watching the work happen,
pre-planned teaching is not required - Master craftsman teaches on the fly
- Master need not remember his work explicitly
- Seeing the work reveals what matters
11Master Apprentice Model
- When you are watching the work happen,
pre-planned teaching is not required - Master craftsman teaches on the fly
- Master need not remember his work explicitly
- Seeing the work reveals what matters
12Master Apprentice Model
- When you are watching the work happen,
pre-planned teaching is not required - Master craftsman teaches on the fly
- Master need not remember his work explicitly
- Seeing the work reveals what matters
- Talking while doing the work reveals details
- Being in the context of work reminds one of many
tasks
13Master Apprentice Model
- Seeing the work reveals structure
- Many instances and many interviews reveal the
picture - Every current activity recalls past instances
14Master Apprentice Model
- Seeing the work reveals structure
- Many instances and many interviews reveal the
picture - Every current activity recalls past instances
- (CD 45)
15Master Apprentice Model
- Apprenticeship suggests an attitude of inquiry
and learning - Humility, inquisitiveness and attention to detail
- Requires no user preparation
16Master Apprentice Model - Differences
- Contextual Inquiry is apprenticeship compressed
in time - Contextual Inquiry tailors apprenticeship to the
needs of design teams - Not do the work, just learn about it
- Not study a single job, but several
- Remaining four sutras guide the adaptation
17Sutras of Contextual Inquiry
- Master apprentice model
- Learn from the master on the fly
- Context
18Context
- Go where the work is to get the best data
- Gather ongoing experience rather than summary
- Gather concrete data rather than abstract data
- Span time by retrospective accounts
19Context
- Avoid summary data by watching the work unfold
- Star Wars Episode III
20Context Summary Vs. Ongoing Experience
- Avoid summary data by watching the work unfold
- Star Wars Episode III
21Context Summary Vs. Ongoing Experience
- Avoid summary data by watching the work unfold
- (CD 47-48)
22Context Abstract Vs. Concrete Data
- Start with real experiences, not abstractions
- You will abstract when you consolidate
- Indicators of abstraction in interviews
- Lean back and look at ceiling vs. lean forward
and handle work - Words generally, we usually or in our
company - Present tense vs. the past tense
23Context Abstract Vs. Concrete Data
- Avoid abstractions by returning to real artifacts
and events - We usually get reports by email. Do you have
one? May I see it? - I usually start my day by reading email. What
are you doing this morning? Can you start? - Sometimes you need to understand things that
happened in the past
24Context Retrospective Account
- Span time by replaying past events in detail
- Tendency to skip details and give summary
25Context Retrospective Account
- Span time by replaying past events in detail
- Tendency to skip details and give summary
- (CD 49-50)
26Context Retrospective Account
- Span time by replaying past events in detail
- Tendency to skip details and give summary
- Look for holes
- Ask questions to fill in the holes
- Use artifacts to provide context
- If story has not yet ended, go back to a story in
the past that did end
27Sutras of Contextual Inquiry
- Master apprentice model
- Learn from the master on the fly
- Context
- Ongoing work, Concrete, Retrospective account
- Partnership
28Partnership
- Traditionally, interviewer has too much power
- You dont know what will turn out to matter
- Apprenticeship model tilts power back to the user
- Interviewer should create a partnership, not
just an apprenticeship - Alternate between watching and probing,
withdrawal and return
29Partnership
- Traditionally, interviewer has too much power
- You dont know what will turn out to matter
- Apprenticeship model tilts power back to the user
- Interviewer should create a partnership, not
just an apprenticeship - Alternate between watching and probing,
withdrawal and return - (CD 52)
30Partnership
- Teach the user how to see work by probing work
structure - Users start interrupting themselves to reveal
aspects of work or discuss design ideas - A partnership develops
31Partnership
- DONT squash design ideas if they arise
- Get instant feedback
- If it works, you understand the work practice and
have a solution - If it fails, you can improve your understanding
of the work - Find the work issues behind design ideas
32Partnership Avoiding Other Relationship Models
- Interviewer / Interviewee
- You ask a question, customer answers and falls
silent, so you ask the next question - You arent there to get a list of questions
answered - Return to ongoing work
33Partnership Avoiding Other Relationship Models
- Interviewer / Interviewee
- Expert / Novice
- You arent there to answer questions. If you
developed the system in use, this is a temptation - Help only if the user is stuck and you cant
observe work - Get back to CI asap
34Partnership Avoiding Other Relationship Models
- Interviewer / Interviewee
- Expert / Novice
- Guest / Host
- Move closer, ask questions, be nosy
- Its a goal to be nosy
35Partnership
- Let the user shape your understanding of the work
- Leads to truly user-centered design
- Partnership creates a sense of shared quest

- Interpretation
37Interpretation
- Interpretation is assignment of meaning to
observation - Good facts are only starting points
- Designs are built on interpretation of facts
38Interpretation
- Interpretation is assignment of meaning to
observation - Good facts are only starting points
- Designs are built on interpretation of facts
- The watchman wont let us in
39InterpretationThe Chain of Reasoning
- Fact
- The observable event (chart next to screen)
- Hypothesis
- An initial interpretation of meaning or intent
(holdover from paper system) - Implication for design
- (numbers dont matter, but accounts should be
unambiguous) - Design idea is realization of implication
- (identify accounts with names only)
40Interpretation
- Fact
- Hypothesis
- Implication for design
- Design idea
- Design is built upon interpretation of facts
- Design ideas are end products of a chain of
reasoning - So interpretation had better be right
- Share interpretations with users to validate
- Will not bias the data
- Teaches the users to see structure in the work
41Interpretation
- Instead of asking open ended questions
- Do you have a strategy to start the day?
- Not particularly.
- give users a starting point
- Do you check urgent messages first, no matter
where they are from? - Actually, things from my boss are important,
because they are for me to do. Messages or faxes
may be for anybody. - Users fine-tune interpretations
- Probe contradictions until assumptions fit
42Interpretation
- Non-verbal clues confirm or negate
interpretations - Yes and Nos
- Huh? way off
- Umm, could be usually means no
- Yes, but or Yes, and depends
- Commit to hearing what the user is actually
saying - People have not had others pay attention to what
they are doing

44Focus
- Focus defines the point of view
- Clear focus steers the conversation
- Everyone in the team should have an entering
focus - Focus lets the interviewer sees more
- Focus reveals detail
- Focus conceals the unexpected
- Focus on one, and loose the other
- Trick start with a focus and then expand
45How to Expand Focus?

47How to Expand Focus?
- Internal feelings guide how to interview
- Opportunities to expand focus
- Surprises, contradictions, idiosyncrasies
- Nods
- Question your assumptions even if they match what
the user says Do they really do that? Why would
they do that? - Internet kiosk operators
48How to Expand Focus?
- Internal feelings guide how to interview
- Opportunities to expand focus
- Surprises, contradictions, idiosyncrasies
- Nods
- What you dont know
- Treat the interview as an opportunity to learn
new stuff - Something technical
- Even if user is not knowledgeable, the extent of
knowledge / misinformation will be useful - Village temple priest
49Focus
- Convert a statement of solution to statement of
user work - Start with explicit assumptions
- Project focus gives the team a shared starting
point - Commit to challenging your assumptions, not
validating them

60Contextual Inquiry Summary
- Running a successful interview is less about
following specific rules than it is about being a
certain kind of a person for the duration of the
interview - Let the four principles of Context, Partnership,
Interpretation and Focus guide you to adapt the
master / apprentice model
61Homework
- Go to the field
- Slums, houses, railway stations, mess kitchens,
post offices, garages, hospitals, - Conduct some contextual inquiries
- Bring back one 10 min long video
- Try to answer these questions
- Why are new solutions required?
- What are the new possibilities in my field?
