Roleplay, Roleplay, Roleplay. Make up some "conflict resolution scripts", grab some pages out of a script, run a 'production meeting'. Practical experiance is far better than talking about it, so get them to call the script, get them to take blocking notation for the script, get them to put together a mini prompt-book etc.
If you don't have a few actors hanging arround, then just get half of the group to be your actors, whilst half do the exercise, then swap.
If you are catering for a wide range of experiance, try to encourage dialogue instead of taking a lecture position. Walk through the entire process. Start with "You have just been approached to work on show X (whatever script you have)" hand it out, "What is the first thing you think we need to do?" and just keep going from there.
Have paperwork from each step in the process to give out as examples.
Make sure any of your "No experiance" SM's keep involved. Don't let the experianced ones steam roll them.
Other than that, good luck :-)
