How does your organization organize projects, teams, boards, etc.?

[Katie Koloj]

I'm a new user in Jira, just starting off in Product Operations. I'd like to learn how other organizations have set up their projects, boards, and epics so I can determine where we can improve. 

We currently have one project that three different teams work from. It works okay enough, but there is a lot of room for improvement, especially around reporting. I've seen many recommendations to have one project with several filtered boards, and some people suggest one board per team or product. And from some initial research I've done, it seems like Advanced Roadmaps might be a good option since high-level reporting on company initiatives is possible. 

But I'm still getting to know Jira and Agile in general. Any advice would be greatly appreciated!
