REL06-BP03: Send notifications (Real-time processing and alarming)

Overview

Implement intelligent notification systems that provide real-time alerts for critical events while minimizing alert fatigue through smart filtering, routing, and escalation mechanisms. Effective notifications ensure the right people receive the right information at the right time to enable rapid response to issues.

Implementation Steps

1. Design Alert Prioritization and Classification

Classify alerts by severity levels (critical, high, medium, low)
Implement business impact-based alert prioritization
Design alert categories for different types of issues
Establish alert ownership and responsibility mapping

2. Configure Intelligent Alert Routing

Implement role-based alert routing and escalation
Configure time-based routing for different shifts and time zones
Design context-aware routing based on alert content
Establish backup notification channels for critical alerts

3. Implement Alert Aggregation and Deduplication

Configure alert grouping to reduce notification volume
Implement intelligent deduplication to prevent spam
Design alert correlation to identify related issues
Establish alert suppression during maintenance windows

4. Configure Multi-Channel Notification Delivery

Implement email, SMS, and push notification channels
Configure integration with collaboration tools (Slack, Teams)
Design voice call escalation for critical alerts
Establish mobile app notifications for on-call personnel

5. Establish Alert Lifecycle Management

Implement alert acknowledgment and assignment workflows
Configure automatic alert resolution and closure
Design alert escalation timers and procedures
Establish alert history and audit trails

6. Optimize Alert Quality and Reduce Fatigue

Monitor alert frequency and response patterns
Implement alert tuning and threshold optimization
Design alert feedback loops for continuous improvement
Establish alert effectiveness metrics and reporting
