Design a flowchart that outlines the step-by-step process of communication during a security incident that affects office operations. Include key decision points for communication escalation, from the initial detection of an issue (e.g., [Security Alert]) to notifying key internal stakeholders (e.g., [Management], [Facilities Team]) and external parties (e.g., [Local Authorities]). Indicate appropriate timing for each step (e.g., first alert within [Minutes] of detection, follow-up updates every [Interval] hours). The flowchart should incorporate escalation rules, such as whether a breach requires immediate action or can be addressed during normal business hours. Ensure that roles are clearly defined within the flowchart for individuals responsible for initiating each communication action.
