This document outlines the responsibilities of both the Cognitive Walkthrough Leader and Evaluators in conducting usability evaluations. Leaders are responsible for planning evaluation methods and facilitating discussions on tasks and responsibilities. Evaluators perform tasks in a given interface, identifying potential errors, utilizing Nielsen’s severity rating scale, and documenting feelings experienced during evaluations. The collaborative process culminates in a comprehensive usability report, summarizing findings and insights to enhance user experience based on usability principles.
