I'll go one further. Almost always. Organizations are basically distributed systems; you theoretically could have fully coordinated decisions with an elegant and efficient network topology (i.e., the decisions involve only those people with relevant information, and don't pass through umpteen unrelated routing layers), but I've yet to see that. Invariably those orgs favoring coordination (CP from a CAP perspective) are slow and inefficient, with too many meetings seeking signoff from stakeholders who have no relevant knowledge or responsibility. The more 'agile' orgs (including suborgs routing around that kind of inefficiency) end up with eventually consistent systems, more AP, and, well, yeah, they're necessarily not coordinated. Hopefully they still have clearly defined areas of responsibility, interfaces, and useful sets of abstraction, but those abstractions are leaky, and the interfaces themselves developed as needs arise.
