Contextual Inquiry and Contextual design

The website for InContext has a lot of background information about Contextual Inquiry and Contextual Design, including a video by Karen Holtzblatt, who developed Contextual Inquiry, introducing Contextual Design. This explanation of contextual inquiry includes an example of conducting a contextual inquiry with a cab driver, and another video showing a contextual inquiry of a shopping trip. This article takes a different approach and considers the relationship between Contextual Inquiry and ethnographic research.


This article introduces four perspectives that personas may take: goal-directed, role-based, engaging and fictional and describes how to create engaging ones.
