The most effective way to test your plan is to conduct exercises. Through exercises you can identify any shortcomings in the plan and ensure that personnel can effectively carry out their roles and expected actions.

The Homeland Security Exercise and Evaluation Program (HSEEP) offers a common exercise policy and provides program guidance that constitutes a national standard for exercises. It also provides useful tools that exercise managers can use to plan, conduct, and evaluate exercises to improve overall preparedness.
