On-call best practices: handoffs, schedules, and alert fatigue

In 2026, building a sustainable on-call program involves carefully selecting rotation models and integrating tools to minimize coordination overhead, thereby reducing alert fatigue and burnout among engineering teams. Key rotation models include Follow-the-Sun for global teams, Primary/Secondary for onboarding junior engineers, and weekly rotations for smaller teams. Effective on-call strategies rely on designing escalation policies that avoid dead-ends, automating coordination tasks, and using a Slack-native platform to streamline incident response. Essential metrics for success include Mean Time to Acknowledge (MTTA), Mean Time to Resolution (MTTR), on-call load, and alert volume per shift, which help identify gaps and justify changes. Tools like incident.io can enhance efficiency by automating incident management tasks, reducing the friction that often burdens engineers during on-call duties.
