For a high-priority incident involving [Product] in [Region], implement a tiered decision-making authority model. Outline three levels of decision-making authority: tactical ([Role1]), operational ([Role2]), and strategic ([Role3]). Define specific actions each level can take, such as [Role1] managing the incident response team and executing predefined containment protocols, [Role2] overseeing broader resource allocation and communication, and [Role3] (e.g., CEO) making the final call on reputational and business continuity concerns. Provide templates for decision documentation, including timelines, actions taken, and outcomes.
