I suspect this is happening because there are less and less qualified people coming into the field. . . And they want more and more different ways to do rather straightforward/simple things (guess the "creativity" thing has resurfaced). I've actually had some of these newer entries into the field complain that they shouldn't have to follow standards. . .I'd love to know the story behind the scenes - I agree it seems as if it could be a potential disaster for all of the production support and/or scheduling teams out there.
If there are multiple ways provided to implement poorly, less will be held accountable for delivering quality work.
Maybe this is just a way to be more "open". . . And soon there may be no controls - just let everyone do whatever they want Kinda like in Win-land. . .
