Looks to me to be more along the lines of grouping together under a single umbrella the four different types of orgs that were used to deliver the transition from the steamers to the Halifax's in the eighties (training: trades and sea; logistics: new needs for the new vessels over their lifetime; combat: tactics and strategy for employment; engineering: manning, maintenance and upgrading over lifetime). The transition at that time had to overcome many bumps in the road that arose because these four orgs did not always talk with one another as much as they should. one such main result was that, while the trade's training for transition got set up, no one looked at the need/usefulness of integrating some trades with one another, or splitting some function from one trade to another, etc, until after some experience was gained.
If a new centralized org charged with transitioning from one type to another for all new vessel types can foresee many of these situations and preemptively deal with them, then it's a good thing. If they only become one more layer of management, it will be a disaster.
