Contextual Inquiry and Ethnography
Contextual inquiry and ethnography study people in their own environments, observing and inquiring into how they actually work and live to ground design in real practice.
Definition
Contextual inquiry is a field method in which a researcher observes and questions users while they perform real tasks in their own environment; ethnography is the broader practice of immersive, in-context study of people's activities and culture, both aimed at understanding actual, situated practice.
Scope
This topic covers in-context, qualitative field methods: contextual inquiry, which combines observation with in-situ interviewing during real work, and ethnographic approaches that immerse the researcher in users' settings to understand practices, culture, and the social organization of work. It addresses how rich situated data is gathered and interpreted. It does not cover out-of-context interviews and surveys, treated separately, nor the design representations that synthesize findings, treated under personas and scenarios.
Core questions
- Why study users in their own context rather than in a lab?
- How does contextual inquiry combine observation with in-situ questioning?
- What does ethnography reveal about the social organization of work?
- How are rich qualitative field data interpreted for design?

Key theories
- Contextual inquiry
- Contextual inquiry treats the user as expert and the researcher as apprentice, observing real work in context and asking about it as it happens, which surfaces tacit practices and breakdowns that users would not report in an abstract interview.
- Situated action
- Suchman showed that people's actions are improvised in response to their concrete situation rather than following fixed plans, a finding that motivated studying real practice in context and reshaped how HCI thinks about work and interaction.
- Design ethnography
- Ethnographic methods adapted for design immerse researchers in users' settings to render the social and material organization of activity visible, providing insight into how technology fits into and reshapes everyday practice.
Clinical relevance
In-context study reveals how people really work, including informal practices and workarounds that surveys miss, which is crucial when designing for complex or unfamiliar settings such as hospitals, control rooms, or specialized workplaces where misunderstanding the context leads to unusable systems.
History
Ethnography entered HCI through workplace studies in the 1980s and 1990s, with Suchman's 1987 work on situated action highly influential. Beyer and Holtzblatt's contextual design packaged in-context inquiry into a practical method, and later texts developed design ethnography, establishing field study as a core way to understand users.

Frequently asked questions
- Why observe users instead of just interviewing them?
- Much of what people do is habitual or tacit, so they cannot fully describe it in an interview, and what they say they do often differs from what they actually do. Observing real work in context reveals these gaps, informal workarounds, and environmental factors that shape how a system must fit in.
- How is contextual inquiry different from ordinary observation?
- Contextual inquiry pairs observation with questioning during the actual work, with the user as expert guiding the researcher. Rather than silently watching or interviewing separately, the researcher asks about actions as they happen, capturing the reasoning and context behind real behaviour.
