Contextual inquiry involves collecting detailed information about customer work practice by observing and talking with the user about the work while s/he works, in the normal context of the work. The researcher ought to stay on the background and let the user lead the situation as much as possible. This means that the researcher tries to form a partnership with customer i.e. learning (but not doing) as an apprentice while the customer is the master of the work. This helps the researcher to understand the customer’s work. The goal is to understand how and why something is done or why something is not done. (Beyer & Holtzblatt, 1998)
