I've been on critical troubleshooting calls with dozens of people. Everyone always has their idea. What works best is to find the person that knows the most about the system and have them lead. Hopefully they have decent communication skills.

Next thing is to have someone watching and taking notes of everything that was performed. As detailed as possible. There's going to come a time where you have to double back.

Then, form a "backlog" of ideas. If people on the call have a suggestion, it gets put on the queue until the current "thread" is seen to the end. This way, people still get to contribute but you're kind of doing a depth first search.

Lastly, deputized person always gets final say, and people should acquiesce, even if they disagree. It's just the only way to really get anything done in those situations. Yeah, it might be inefficient if they're going down the wrong path, but it's entirely more inefficient to have a dozen people suggestion alternatives and trying them all in a half-assed way.
