Contextual inquiry


Contextual inquiry is a user-centered design research method, part of the contextual design methodology. A contextual inquiry interview is usually structured as an approximately two-hour, one-on-one interaction in which the researcher watches the user in the course of the user's normal activities and discusses those activities with the user.

Description

Contextual inquiry defines four principles to guide the interaction:
If specific tasks are important, the user may be asked to perform those tasks.
A contextual interview generally has three phases, which may not be formally separated in the interview itself:
Before a contextual inquiry, user visits must be set up. The users selected must be doing work of interest currently, must be able to have the researcher come into their workplace, and should represent a wide range of different types of users. A contextual inquiry may gather data from as few as 4 users to 30 or more.
Following a contextual inquiry field interview, the method defines interpretation sessions as a way to analyze the data. In an interpretation session, 3-8 team members gather to hear the researcher re-tell the story of the interview in order. As the interview is re-told, the team add individual insights and facts as notes. They also may capture representations of the user's activities as work models. The notes may be organized using an affinity diagram. Many teams use the contextual data to generate in-depth personas.
Contextual inquiries may be conducted to understand the needs of a market and to scope the opportunities. They may be conducted to understand the work of specific roles or tasks, to learn the responsibilities and structure of the role. Or they may be narrowly focused on specific tasks, to learn the details necessary to support that task.

Advantages

Contextual inquiry offers the following advantages over other customer research methods:
Contextual inquiry has the following limitations:
Contextual inquiry was first referenced as a "phenomenological research method" in a paper by Whiteside, Bennet, and Holtzblatt in 1988, which lays out much of the justification for using qualitative research methods in design. It was first fully described as a method in its own right by Wixon, Holtzblatt, and Knox in 1990, where comparisons with other research methods are offered. It is most fully described by Holtzblatt and Beyer in 1995.
Contextual inquiry was extended to the full contextual design methodology by Beyer and Holtzblatt between 1988 and 1992. Contextual design was briefly described by them for Communications of the ACM in 1995, and was fully described in Contextual Design in 1997.
Work models as a way of capturing representations of user work during interpretation sessions were first briefly described by Beyer and Holtzblatt in 1993 and then more fully in 1995.
