Like any other quality attribute, usability imposes specific constraints on software components. Features that raise the software system's usability level have to be considered from the earliest development stages. However, discovering and documenting usability features is likely to be beyond the usability knowledge of most requirements engineers, developers and users. We propose an approach based on elicitation patterns that capitalise upon key elements recurrently intervening in the usability features elicitation and specification process. Pattern use furnishes requirements analysts with a knowledge repository that helps them to ask the right questions and capture precise usability requirements information.
