概要	The Pluralistic Walkthrough is a usability inspection method that brings together users, developers, and usability specialists to walk through an interface and voice their reactions and concerns. Developed by Randolph Bias in 1992, this method combines elements of cognitive walkthroughs with user involvement, creating a collaborative evaluation setting that captures diverse perspectives. By including actual users in the evaluation session, the method bridges the gap between expert judgment and real-world user experience, uncovering unexpected insights and building stakeholder consensus around design improvements.	Contextual Inquiry is a field research method for understanding users by observing and interviewing them in their real work environment. Developed by Hugh Beyer and Karen Holtzblatt at Applied Research and Technology, this method combines ethnographic observation with targeted questioning to capture not just what users say they do, but what they actually do—including workarounds, informal practices, and priorities often invisible in lab settings. Contextual Inquiry uncovers the context, constraints, and real-world complexity of user tasks, providing rich insights for user-centered design.
