What is on-call scheduling?

On-call scheduling is the practice of assigning IT staff to be available outside of normal business hours to respond to incidents, outages, or other urgent issues. When you're on-call, you're essentially agreeing to be reachable and ready to spring into action at a moment's notice.

I remember my first on-call rotation as a junior developer. I was nervous, constantly checking my phone, and jumping at every notification. But over time, I learned that being on-call isn't about being stressed 24/7 - it's about being prepared and having systems in place to handle issues efficiently.

The main goals of on-call scheduling are:

1. Ensuring continuous system availability
2. Minimizing downtime and service disruptions
3. Providing timely incident response
4. Distributing workload fairly among team members

On-call duties typically involve:

• Monitoring alerts and notifications

• Troubleshooting and resolving issues

• Escalating problems when necessary

• Communicating status updates to stakeholders

Types of on-call schedules

There are several common types of on-call schedules, each with its own pros and cons:

1. Primary/secondary rotation

   • A primary on-call person handles most issues
   • A secondary backup is available if needed
   • Pros: Clear responsibilities, built-in redundancy
   • Cons: Can be taxing on primary responder

2. Follow-the-sun

   • Leverages global teams across time zones
   • Each region handles on-call during their daytime hours
   • Pros: 24/7 coverage without night shifts
   • Cons: Requires large, distributed team

3. Weekly rotation

   • Team members rotate on-call duties weekly
   • Pros: Predictable schedule, longer recovery periods
   • Cons: Full week of being on-call can be draining

4. Daily rotation

   • On-call responsibilities change daily
   • Pros: Spreads burden, frequent breaks
   • Cons: Less continuity, more handoffs

5. Shift-based

   • Set shifts (e.g. 8am-5pm, 5pm-12am, 12am-8am)
   • Pros: Clear boundaries, works well for 24/7 teams
   • Cons: Night shifts can be difficult

The best schedule depends on your team size, geographic distribution, and workload. I've found that a weekly rotation with a primary/secondary system works well for many teams, but don't be afraid to experiment and find what fits your specific needs.
