“The Information-Sharing Environment Analysis (ISEA) is a process jurisdictions can use to identify and chart their information-sharing environment as it pertains to standard operating procedures (SOPs), policies, and systems. A comprehensive ISEA can be conducted in coordination between DHS’s office of Grants and Training (G&T) Exercise Division and the Prevention Technical Assistance Program (PTAP). The ISEA should be administered at the appropriate level (e.g., State, local, or regional) prior to an Initial Planning Conference (IPC) of a prevention exercise. The ISEA is an informative method that seeks to develop the picture of the jurisdiction’s prevention landscape by answering the following questions: (1) What activities encompass all of the exercising jurisdiction’s antiterrorism efforts (e.g., outreach programs, internal initiatives, personnel job responsibilities) ? (2) What agencies, departments, units, and programs support and lead these activities? (3) What are the narrowly defined purposes of each of these organizations’ participation in these activities? (4) What are the administrative, communication, implementation, and interoperable systems that connect these organizations? (5) How are these systems physically built, populated with information, accessed by partners, and trained upon? What is the narrowly defined purpose of each system?” (DHS, Homeland Security Exercise and Evaluation Program, Volume V: Prevention Exercises (Draft), December 2005, p. 6)
