ReadyZoneHQ deisgned, developed, conducted and evaluated a Department Operations Center (DOC) Functional Exercise (FE) for the Hawaii Department of Health (HDOH). The goal of the exercise was to ensure that HDOH had the ability to effectively and efficiently synchronize efforts with other offices/divisions in response to a Category IV hurricane in accordance with relevant plans and procedures. The exercise assessed the following Public Health Preparedness (PHEP) Capabilities: Emergency Operations Coordination, Information Sharing, Community Recovery, and Mass Care. ReadyZoneHQ provided a simulation cell (SIMCELL) to increase realism for participants, and stress the ability of the DOC to respond to injects received through multiple communications channels. ReadyZoneHQ provided a detailed After Action Report/Improvement Plan (AAR/IP), and conducted an After Action Meeting (AAM) with stakeholders to review issues identified during the exercise.
