Contextual inquiry (CI) is a user-centered design (UCD) ethnographic 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 do their normal activities and discusses what they see with the user. ==Description== Contextual inquiry defines four principles to guide the interaction: * Context—Interviews are conducted in the user’s actual workplace. The researcher watches users do their own work tasks and discusses any artifacts they generate or use with them. In addition, the researcher gathers detailed re-tellings of specific past events when they are relevant to the project focus. * Partnership—User and researcher collaborate to understand the user’s work. The interview alternates between observing the user as they work and discussing what the user did and why. * Interpretation—The researcher shares their interpretations and insights with the user during the interview. The user may expand or correct the researcher’s understanding. * Focus—The researcher steers the interaction towards topics which are relevant to the team’s scope. 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: * The introduction—The researcher introduces him or herself and shares their design focus. They may request permission to record and start recording. They promise confidentiality to the user. They solicit a high-level overview of the user’s work. They agree with the user on the specific tasks the user will work on during the interview. * The body of the interview—The researcher observes the work and discusses what they see. They take notes, usually handwritten of everything that happens. * The wrap-up—The researcher summarizes what they learned from the interview, offering the user a chance to give final corrections and clarifications. 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 (wherever it is), and should represent a wide range of different types of users. A contextual inquiry may gather data from as few as 4 users (for a single, small task) 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 (defined in the Contextual design methodology). 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Contextual inquiry」の詳細全文を読む スポンサード リンク
