Hello Jeri,
For starters, don't teach people about ISO, teach them about your quality system. One of the worst things you can do for your company is to allow them to separate ISO from the rest of what you do. It's your quality system, ISO is just a portion of it.
As for some of the more fun things.... here's a few that I've done, the sky's the limit so go crazy:
1 At meetings - ask questions that might be asked during an audit, give the first person to answer the question a candy bar.
2 Walk around asking folks if they know the quality policy - give them a sticker to wear on their hard hat if they know it, if they don't just tell them to stop by your office once they've learned it and you'll give them their sticker (this helps to get people familiar with coming into your area also)
3 Do a lot of management by walking around, ask questions about what people are doing, and try to find out some info about them outside of the work area. Folks love it when you remember who they are and that they won the company golf outing.
4 Hand out some quality posters to put in highly visible areas.
5 There is a thread that tells about quality games and stuff, search through those and you'll find some you can use.
6 Challange different areas to contests of your choosing, put the winning team's foto in the company newsletter.
7 Go to the crew meetings, ask for a 5 minute time slot and do a quick "this is what we are doing" overview.
8 Most of all, whatever you do, make sure that:
you act like you are committed to quality,
you let everyone know it is a team effort and you cannot live without their input,
keep life fun, nothing is as boring as managing a system, so continue to find ways to keep it light.
Hope that this gives you some ideas.
