Abstract: A system and method of providing a graphical depiction of an entire emergency response process via a computer generated emergency response synchronization matrix. The matrix provides for real-time adjustments of the complex emergency response system, which can be viewed on a computer screen or in printed form. The matrix also provides for planning in “negative time”, with reference to the time of the emergency incident, effectively controlling the decisions and actions that must be made and taken before the disaster occurs. The synchronization matrix and the method of generating and implementing the matrix are effective tools in optimizing the planning, exercising, and implementation of emergency response plans, taking into account the interaction of a plurality of independent organizations whose actions and decision will effect the actions and decisions of other organizations in the emergency response process.
