My personal system is to have as little intervention as possible unless absolutely necessary.
I'm Twiddle by the way.
Usually, my missions are structured in such a way that it is entirely up to the players to organize--self sufficient leaders. I am not there to babysit them, I am there to make a mission.
The absolutely necessary part comes in when the mission has derailed, people are being crazy, etc.
My most recent experience of this was a Stratis Syndikat mission, where the team members began 'rebelling' against Syndikat, killing our objective, etc.. After giving them a couple mulligans, I decided to roll with it. Solomon got unhappy and sent an extermination squad to eliminate them, due to their gross incompetence and defection from Syndikat. Non defectors could flee via boat while extermination squads executed all of the traitors, before a mission fail.
Just one example of intervention.
