designed to be used iteratively, earlyin the design cycle, by individuals orgroups. Either software developersor usability specialists can performthe Walkthrough. It is a task-basedmethodology that serves to focus anevaluators attention on the users

goals and actions, and on the systemaffordances that support or hinderthe effective accomplishment ofthose goals (Wharton, et al., 1992)
