As a designer who's worked with both marketers and engineers (and not forgetting customer support folks), I can definitely relate! I think a working relationship that’s driven by humility and empathy helps everyone focus on creating better work together.
Another point I'd add (from a designer's perspective) to get different teams on the same page is that, cross-team collaboration and communication can often be made more effective and richer simply by using whiteboard and markers during discussions. Having something visual to point at and talk about makes it easier for everyone align themselves to each other’s lenses, and also reduce misunderstandings that drive people crazy.
