Information systems actability theory builds on a communicative action perspective on IS. Information systems are seen as instruments for technology mediated work communication. Human actors are communicating (i.e. sending and/or receiving messages) through an information system. Information systems actability emphasises pragmatic dimensions of information systems. The paper presents 19 actability criteria divided into three groups: 1) criteria concerning user-system interaction, 2) criteria concerning user-through-system-to-user communication, and 3) criteria concerning information systemâ€™s contribution to workpractice processes. These actability criteria should be possible to use in design and evaluation of information systems.
