Commissioning per NFPA 3, but what's that? I see it on a list with "Easter Bunny", "Tooth Fairy" and "Great Pumpkin".

So without points and without a procedure to follow, I think we're talking infancy. However, I live in the sticks- but I do get out occasionally ;) and occasionally communicate with others in the business when we venture across the county line :) I'm not hearing anything approaching Cx being mainstream.
