Epic analysts - need input on our implementation

We're currently going through a foundation implementation of Epic, and it's honestly a complete mess. Not at all what I expected from the Epic team of AC/AM's. As a Bridges analyst I'm forced into daily calls to give updates about interfaces that we cannot build because other teams either haven't had any calls set up with the vendor, or the contract is still in process.

Our Orion tasks and building blocks are a hodge-podge of random things to track down that other teams are responsible for, or that workgroups should be deciding but aren't.

Frustrated isn't even the right word. At this point it's just annoying. Does Epic just talk a good game or is this out of the ordinary? It seems like nobody at Epic is talking to one another and all they are concerned with is checking off boxes to meet deadlines and hammering our staff but providing next to zero help.
