This document discusses decision making support during crises. It notes that problematic information sharing between strategic, operational and tactical levels during disasters leads to uninformed decisions. It also says that different disciplines acting separately and scattered command causes unnecessary casualties. The document proposes solutions like stable communication between all levels to make informed decisions, integrated cross-border approaches, and unified command to reduce casualties. It advocates for a shared decision making platform that is accessible, secure, scalable, resilient and allows both offline and online synchronization to strengthen joint efforts during crises.
