It's also an evidence based on the data I'm collecting. But not in the Information Systems literature, where the research work «assumes» that workers use (only) the organizational systems to get work done. «Assumes» in here refers to the fact that personal artefacts are not part of the conceptual models of Information Systems (IS) nor are the other spaces that workers use to get work done. Maybe this can be seen as deliberate absence of something (John Law, 2004).
