When managing a multi-department incident involving [Product] in [Region], ensure that decision-making authority is clearly defined across all departments. Specify the role of each department, such as [Role1] (e.g., Public Relations Lead) making decisions on external communications, [Role2] (e.g., Customer Support Head) managing customer-facing responses, and [Role3] (e.g., IT Incident Response Lead) handling technical containment and remediation. Create a cross-functional decision-making flowchart to visually represent authority and communication pathways. This flowchart should include decision points, potential escalations, and required sign-offs from senior leadership.
