It depends. I’ve managed major incidents with hundreds of participants.

Our major incident process generally had a “suit” call with non-technical executives and people who would be coordinating customer triage, outreach, etc. Then we would have a tech bridge where the key stakeholders did their thing.

We used the Federal incident command system as a model. It’s a great reference point to use as an inspiration.

Any guides on the "Federal incident command system" to read from (e.g. without blindly googling for it). Thanks?

In addition, you can look into ITIL/ITSM Incident Management plans, they have well developed process structure to work from as a guideline.

I have also seen organizations recommend Kepner Tregoe method training for real time high pressure problem solving based off Nasa Mission Control systems.
