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.
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.
