The parts
| Decision | A good default |
|---|---|
| First channel | A push to a phone app with an acknowledge button |
| Wait before calling | 5 minutes |
| Second channel | A phone call, because pushes get missed in sleep |
| Wait before the next person | One more step (5 minutes) after the call |
| Who is last | Someone senior who would rather be woken than not |
Common mistakes
- Paging a whole channel: everyone assumes someone else has it.
- Escalating noise: if it shouldn't wake person one, it shouldn't wake person two.
- No floor: a rule that can turn off alerts for a dead app will, eventually.
Pagerless's defaults are the table above. See levels.
