My understanding is that even a fully trained ASA controller takes 12 months to be fully trained in a new port/position. This is not an area where you can apply the quick fix bandaid solutions that are all the modern manager is capable of, in aviation or other industries.
Across Australian business, crisis management and crossed fingers have kept a lot of morons in new Mercedes and most of the time they get away with it, but you can't just 'strategize for new paradigms or whatever's trendy this week'
and supply a ready number of ATCs for a given position overnight, no matter how many 'incentives' you offer and how much you stamp your little Ferragamos.
