Emergency management exercise cycle

This circular arrows diagram sample shows the exercise cycle stages: 1) Strategy plan, 2) Design and development, 3) Conduct and evaluation, 4) Improvement planning. It was designed on the base of the diagram on the Emergency Management Insitute training IS-120.b webpage from the website of the Federal Emergency Management Agency (FEMA) of the United States Department of Homeland Security.

"Exercises give communities, states, and regions a set of essential tools to prevent, prepare for, respond to, and recover from disasters." [emilms.fema.gov/ IS120A/ module0.htm]
"Disaster management (or emergency management) is the creation of plans through which communities reduce vulnerability to hazards and cope with disasters. Disaster management does not avert or eliminate the threats; instead, it focuses on creating plans to decrease the effect of disasters. Failure to create a plan could lead to human mortality, lost revenue, and damage to assets. Currently in the United States 60 percent of businesses do not have emergency management plans. Events covered by disaster management include acts of terrorism, industrial sabotage, fire, natural disasters (such as earthquakes, hurricanes, etc.), public disorder, industrial accidents, and communication failures."

The diagram example "Emergency management exercise cycle" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Circular Arrows Diagrams solution from the area "What is a Diagram" of ConceptDraw Solution Park.
