Ethnography
The systematic study and documentation of human activity
• without imposing a prior interpretation on it• via immersion in the environment of it• and observation of the routine tasks that comprise it
“Make the implicit explicit”

Ethnography & Design
Ethnography of design• Studies of developers and their environments
Ethnography for design• Use of ethnography results to inform the
development of designs (e.g., ethnomethodology, technomethodology)
Ethnography within design• Integration of ethnographic techniques into the
development process itself

Advantages
Describes how work is accomplished, in practice, rather than how it is planned or how individuals report the accomplishment of their work
Recognizes the importance of the context and environment on activities
Recognizes that, although situations may have superficial similarities, they are actually unique

Disadvantages
Time-consumingDifficult to translate between the language of
sociology and the language of technologyResults depend critically on the skill of the
ethnographic observer, as well as the analytic methodology

Using Ethnographies in Design
Framework (Hughes et al., 1997)• Characterize ethnographic results in a way amenable
to designer’s needs• Dimensions
– Distributed coordination– Plans and procedures– Awareness of work
Methods• Designers use ethnographer’s documented results• Designers learn ethnographer’s methods

Methods
Applying ethnography to design
Coherence Method• tries to facilitate the identification of a product’s
most important use cases• by structuring the analysis of data
Contextual Design• tries to facilitate the application of fieldwork results
to product design• by structuring the data for analysis

Coherence
Viewpoints• Derived from dimensions identified
– Distributed Coordination– Plans and Procedures– Awareness of Work
• Guides the observer to particular aspects of the workplace
• Allows several perspectives on a particular design to be investigated and reconciled
• Intended for the early stages of design process to inform the models underlying the eventual design

Contextual Inquiry
Approach• Apprentice Model: the designer works as an “apprentice” to
the userUnderlying Principles
• Context• Partnership• Interpretation• Focus
Method• Contextual interview

Work Modeling
Aspects to be modeled• Work Flow• Sequence• Artifact• Cultural• Physical

Developing Work Models
Each analyst has a different understanding of the session and they have to be reconciled into a common view of the work
Interpretive Roles• Interviewer• Modelers• Recorder• Moderator/Facilitator• Rat-Hole watcher

Consolidation
Affinity diagram• Organize individual notes from interpretation
discussion• Groups of notes, similar in some way, emerge from
the data (induction)Work Models
• Consolidate a model that’s valid across individuals• Aim is to identify key roles, common ways of doing
work, and adaptations to specific contextsDesign Room
