Abstract: In order to better understand the challenges specific to the deployment of collaboration technologies in crisis situations, we conducted an informal observational study of the deployment of Groove Virtual Office to various civil and military groups at the heart of the disaster zone over the course of ten days. We summarize both general lessons learned from observations of social and communication challenges in crisis situations that impact technology adoption, and make specific recommendations for improving the deployment process of Groove to enable cross group collaboration. We generally found that dynamic, informal social networks and lightweight ephemeral work groups were essential social structures in the relief effort, and we discuss the need to innovate technologies to support these alternative types of organizations. We encourage that current technology centric innovation for ephemeral workgroups is complemented by a usage centric approach to help address emergent behaviors and opportunities.
