We haven't discussed it much on this forum, but something I've wondered about is, after WGAC achieves its "goal" - then what? Judging from what I know of their alignment with the other checklists (admittedly little), especially the "base" IOC that they started from, it seems that in theory they are very welcome to both "bottom up" suggestions from local organizations and "top down" review of newer research... especially in those geographies without a robust advisory effort. It's not necessarily an either/or problem.
BUT, there is something to add to the management problem metaphor here - what if one of your satellite offices has vastly different procedural norms than the rest of your offices? And they don't want to change? And that office happens to cover the entirety of the New World? Do you accept that office doing their own thing, or do you override them at "corporate level?"
