The document discusses BlackBerry AtHoc's personnel accountability software. It highlights that traditional mass communication is no longer sufficient and organizations need solutions to efficiently account for personnel. The software provides real-time notification and response capabilities. A case study shows it was used by the US Army to warn, account for, and recall over 40,000 personnel in Europe following the Brussels attacks in under an hour. Lessons showed alerts alone are not enough and automated accountability is crucial for safety. BlackBerry AtHoc aims to address this with its comprehensive solution for notification, response collection, and situational awareness across organizations.
