A lot of places have timetables for what's supposed to happen during an incident, for example:
- If the issue is ongoing within an hour, inform only designated individuals
- If the issue is taking longer than an hour or up to two, inform stakeholders
- If the issue looks likely to leave systems offline for longer, arrange meetings every thirty minutes to keep stakeholders updated
Though not consistent anywhere I've worked, good companies have plans in place to make sure everyone is on the same page, and better places don't invite the troubleshooting engineers to these meetings, instead designating a liaison who gets the information from the engineers while they're working.
