The public sector and emergency response worldwide face budget constraints and lack of resources while having to respond to an increasing number of emergenices. In this chapter, we will describe how the Swedish municipal fire services have addressed this challenge by initiating a first response with new ways of organizing their response units and through collaborations with other societal sectors, i.e., semiprofessionals and with citizen volunteers. This, by using experience from a ten years period and analyzing it in terms of cross-sector collaboration and coproduction. The chapter includes different emergency types the new resources can be dispatched to, with a specific focus on residential fires. The results show that the major benefit for all three forms of reorganization is a shorter response time, which can lead to more saved lives, reduced human suffering, and less material damage. When using semiprofessionals and volunteers, identified challenges include, e.g., prioritization of tasks, making the engagement collective, the dispatch technology, and avoiding risky situations. We discuss the implications of the results and provide some suggestions for future work.
