> the focus is on the object rather than the process

From a business apps point of view, this is exactly it. You might find that methods are subordinate to objects, but in the business domain itself, the objects themselves are manipulated by processes. It's a whole other layer above the OO layer, and failure to realise this means you either end up with lots of FooManager classes, or you push overarching responsiblities back down into low-level objects that don't really want them, and find you have too much coupling and not enough Demeter

(Of course, you might be writing FooManager classes with this upper layer explicitly in mind - in which case fair enough and you'll probably like DCI. But I think there's still a lot of mileage in plain ordinary functions that don't have to belong to anything)
