Identification criteria in task modeling

Abstract

Task modeling consists of a fundamental activity that initiates usercentered design in user interface development. It is therefore important to reach the best task model possible and that the task modeling activity remains consistent when the task modeler changes. For this purpose, this paper introduces a set of criteria in order to identify tasks during task modeling in an unambiguous way that results into a task model exhibiting desired properties of quality such as completeness, consistency. In addition, starting and stopping criteria provide designers with guidance on when and how to start and finish the task modeling. © 2008 Springer Science+Business Media, LLC.
