Implementing policies for categorizing and communicating alerts based on severity helps team members prioritize their responses, ensuring that critical issues are addressed promptly while preventing alert fatigue caused by numerous non-critical notifications. Enabling alerts during maintenance mode does not reduce fatigue because it might result in unnecessary alerts during planned downtimes. Disabling alerts outside of business hours could lead to missed critical incidents. Configuring alerts to trigger less frequently will likely delay the response to critical issues, which could result in system instability or downtime.
