Crisis management (CM) situations are most-often complex and dynamic, and require team members to make optimal decisions under constraints of high risk, uncertainty, high workload, and time pressure (see, e.g., Brehmer, 2007). An Edge Organization (EO) is an adaptive, rapidly reconfigurable, and distributed team structure in which no roles are previously assigned, and resources are not distributed in advance. Such a team structure is assumed to be able to improvise and respond quickly to emerging problems. We used the C3Fire CM simulation to measure the coordination (of units and resources) efficiency amongst edge team members. Twenty-four teams of four participants completed four C3Fire scenarios, each lasting 10 minutes. Results revealed that team members achieved better coordination as they progressed through the scenarios. This learning effect suggests that it could be beneficial to train team members to coordinate their actions efficiently and fully exploit the potential agility provided by EO.
