ISO Man, welcome to the Cove.
You really have a choice to make here - you can do a "canned" ISO presentation, that will very possibly bore your collegues to tears, or you can make a quick presentation about YOUR system. The second option will be much more effective because it will be about what will affect your people on a day-to-day basis.
I have done both kinds of presentations, and have never really felt the first approach was even close to effective. Sure, the folks will have heard about ISO, but after a type-1 presentation starts, eyes start glazing over about 2-3 minutes into the show. I even had 1 person start snoring.
My advice is to write your own. Have fun with it.
