On-Call Program Evolution: Three Stages of Maturity

On-call programs are not equal. The maturity stage decides what investment yields what return.

Why stages exist

Programs converge on similar shapes as they mature. Knowing your stage helps prioritize the right next step.

Skipping stages produces brittle programs.

Stage 1: ad-hoc

• Whoever was on-call last is on-call now. No formal rotation. Tribal knowledge.
• Common in early-stage startups. Burns out the early hires.

Stage 2: structured

Formal rotation; documented runbooks; alerting hygiene.

The middle stage; most teams sit here. Sustainable but improvable.

Stage 3: optimized

Quiet rotations; metrics-driven tuning; structural compensation. Burnout near zero; recruiting wins on the program.

Few teams reach; the difference is investment over years, not months.

Antipatterns

• Stage 1 forever. Burnout grows.
• Skipping straight to Stage 3. Brittle without Stage 2 foundation.
• Stage 3 declared without earning it. Performative.

What to do this week

Three moves. (1) Apply this practice to your next on-call rotation. (2) Survey the team after one cycle. (3) Iterate based on feedback; the discipline is the cadence.
