This paper examines the nature of events within task analysis. It draws on three roots: Groupware Task Analysis, Trigger Analysis and Status-Event Analysis. Each of these considers events and the way these enable or initiate activities, but they have subtly different understandings of these. Analysing both these distinctions and also the common features between them has lead to a deeper theoretical understanding of the ontological nature of events (and their relationship to activities/tasks), the attributes of these events (e.g. whether they originate internal/external to the task context), and the relationship between the events and tasks (e.g. different kinds of enablement/triggering).
