How to Communicate With Developers With Object Maps

I hear all the time that this process is a great way to help communicate with developers I mean you're saying that. Is there any sticky points or like any kind of like, not risk is it the right word but when you any any things to watch out for as far as terminology or even framing the exercise? It's super important to talk about the relationships and how the data is going to come across from multiple objects at a time. But I haven't had too many conversations where I've like had an issue communicating with the developer when I'm using this so it's hard to say what. I'm just sticking points to watch outFor.
