I want wondering if anyone can help to clarify the use of Resource Breakdown Structure and Organization Breakdown Structure, as well as RAM and Project Team Assignments. I know they are not all the same, but they contain similar information. To me, Resource Breakdown Structure has nothing to do with the work package, it just like an organization chart, but breakdown in a certain way. But OBS is the one that actually links the work package to the resources. But I feel like RAM is kind of showing similar information, but in a grid manner.

Thank you so much,
