This is an intro to the idea. Basically, the learning was that it appears that loosely-coupled systems are easier to maintain and evolve. One should of course not read too much into the definition of "loosely-coupled" -- what one means here is that the "interface" between two components is well-defined and each party knows about it. However the other party knows nothing about what happens under the hood of the interface. Such systems are easier to maintain because the references of one object are not tied together with the references of another object, but rather they pass through well-defined interfaces.
One may also see that the same idea can be extended to hold true for more general relationships e.g. Loosely-coupled organizations may be better suited for evolution/adaptation and growth than tightly coupled organizations i.e. organizations that do not play the big-brother may allow each employee to learn/grow as per their personal choice thereby increasing satisfaction levels and motivation (because of having the perception of being in control of one's life).
Further, it may also be that in some enterprises "identity" management/aka "authorization" is tightly coupled and "authentication" is loosely coupled i.e. one can get in from many doors (the edge is only loosely coupled with the centralized system), but cannot access any content unless the centralized server approves [Ref: [1] [2]]
