> It's probably just enough to dress them in business casual…

Bonus points for how little effort you can get the actors to put in while still getting away with it. Just have them wear shorts, some tech vendor t-shirts, and put most of them in a conference room, while two people talk about the last “feature” release.

If it’s not a tech related portion of the business, do the same, but say something about making casual “insert-day-of-the-week” and have said business group talk about how the last “feature” release impacted their section.

Triple bonus points if you get the boss to join in on the discussion with no one knowing what the actual “feature” released was, without the boss figuring the whole thing out.
