Thanks for the feedback. To give you more insight of that situation : The upper circle is the GCC.
1. Historically speaking, some roles in that circle are not really connected together (was already the case in the previous hierarchical situation) and some are not in the heart of the GCC main purpose
2. Some of those roles became big enough to be mutated into circle.
@Jean-Michel, I understand the idea of "should be clearly separated". But as they are initially in the GCC, I don't see right away how I should/could propose this, and where should I "send" those !
