Abstract: This paper presents a study of the role of artefacts in sensemaking during emergency response. A qualitative study was conducted with two UK Police Forces, with a particular focus on the role of artefacts in the creation and modification of sensemaking frames. This research demonstrates that sensemaking is a key component of emergency response Command and Control and that this activity is distributed across the individuals within the system. Collaborative sensemaking is coordinated via social and organisational means, supported by a range of private (informal) and shared (formal) artefacts, which function as resources for action – cueing frame seeking and frame-defined data collection. The study also reveals the role of narrative in bridging the gap between these two parallel sensemaking processes and raises implications for the further digitisation of the emergency response environment, demonstrating the importance of balancing social and technical factors in the design of ICT for emergency response. © 2012 ISCRAM.
