Create distinct communication protocols for different incident severity levels, ranging from [Low Severity] to [Critical Severity] incidents. For each severity level, specify the communication channels to be used, frequency of updates, and key stakeholders to be notified. For instance, low-severity incidents may require email updates, while critical incidents may necessitate instant messaging and real-time teleconferences. Ensure that each response team member knows their communication duties at each severity level, such as daily or hourly reports, and how the protocol scales as the incident evolves.
