  • Asking for Opinion about the system
  • Natural Interruptions and Movement

5
Field Interview
  • Observation and Discussion
  • Interruption
  • Taking Notes
  • Recording Information
  • Collecting Artifacts
  • Sharing design ideas
  • Drawing physical workplace

6
Wrap-up
  • Summarizing and Validating our ideas
  • Giving tips on system use
  • Asking them whether we can contact them later for
    further information
  • Telling them that they can contact us if they
    find more information
  • Thanking the users

7
Analyzing Interview Information
  • Preparing Team Room
  • Transcribing the Interview
  • Fixing and Evolving the Focus of Analysis
  • Interpreting the Information
  • Recording Understandings
  • Structuring the Understanding
  • Sharing Session

8
Preparing Team Room
  • Permanent or Temporary Place
  • Required Equipments
  • Computer with required software
  • Projector or large monitor
  • Flipchart to capture work models or team
    discussions
  • Red, blue and green color pens for capturing
    models

9
Transcribing the Interview
  • Fresh in memory
  • Reviewing interview
  • Including comments, insights and questions

10
Fixing and Evolving the Focus of Analysis
  • Clarifying the focus at the beginning
  • Deciding what to include and exclude based on the
    focus
  • Looking for answers from the transcript
  • Validation of interpretation of post-interview
    analysis
  • Review of the question for setting next entering
    focus

11
Interpreting the Information
  • Changing focus, revealing of different aspects
  • Reading transcript text and sharing design ideas
  • Developing an integrated understanding of user
    work

12
Interpreting the Information (cont.)
  • Gathered knowledge is reusable
  • Framework
  • Work structure or work flow
  • Problems doing the work using the system
  • Disruptions caused by the system
  • Workarounds that are used to avoid disruptions
  • Transparency of the system
  • Aspects of work process and system use that
    support work

13
Recording Understanding
  • Coding scheme
  • Post-its or note card
  • Reviewing interview one at a time

14
Recording Understanding (cont.)
  • Description of users work
  • Flow or structure of the work
  • Description of problems of work and with the
    computer tools
  • Design ideas from the understanding of their work
  • Questions for following interviews

15
Structuring the Understanding
  • Dividing the Post-its
  • Systematically grouping Post-its
  • Affinity Diagram

Sharing Session
  • Team members
  • Stakeholders

18
Benefits of Arranging Contextual Interview
  • Multiple interviewers
  • Different perspective
  • If recording permission is not available
  • Setting focus deciding which information to
    include and which to exclude

19
Problems of Arranging Contextual Interview
  • Real Workplace
  • Time Limitation
  • Wrong Person
  • No-show User
  • Recording Permission
  • Multiple interviewers reduces the number of
    interview

20
Benefits of Conducting Contextual Interview
  • Idea about the real use
  • More information from observation and interview
  • Questions are not preset detail information can
    be collected
  • Interruption helps in gaining the focus
  • Sharing idea validates the understanding

21
Problems of Conducting Contextual Interview
  • More focus on conversation than activities
  • Getting more information reaches overload point
  • Current activity may not be helpful

22
Benefits of Analyzing Contextual Interview
Information
  • Transcript helps to analyze
  • Fixing and evolving focus helps to set entering
    focus for next interviews
  • Interpreted information is reusable
  • Reusable information provides us a proper idea
    about the using of the system

23
Benefits of Analyzing Contextual Interview
Information (cont.)
  • Recording understanding helps to recall the
    interview idea later
  • Sharing session
  • Team members missed interpretation session
  • Sharing interpreted information with management
    or stakeholders
  • Adding missing information to the models or
    Affinity diagrams

24
Problems of Analyzing Contextual Interview
Information
  • Getting room for analysis
  • Transcribing is time consuming

25
Worked-through Example
  • System Internet Explorer
  • Users Students

26
Arranging Interview
  • Talking to the school management
  • Setting focus to get users problems
  • Asking permission for using lab and recording

27
Conducting Interview
  • Introduction with the users
  • Informing them about the interview focus,
    schedule and procedures
  • Setting up the recorders
  • Asking for their opinion about this browser

28
Conducting Interview (Cont.)
  • Asking to perform regular tasks
  • Observing them
  • Asking questions about the tasks and problems
  • Gaining the focus if the conversation is out of
    track
  • Sharing understandings
  • Thanking them

29
Analyzing Information
  • Preparing room
  • Transcribing interview information
  • Fix our focus
  • Using Post-its method
  • Recording understandings
  • Using Affinity diagram
  • Sharing session
