This is organizational problem that should be solved so that meetings are avoided as much as possible. The main way I have seen this solved is by engineering teams having clear APIs between. I use the term API loosely. This may be a software API between software teams but it may be a document, hardware interface or other sort of interface.

Without this sort of structure, communication requirements grow quadratically with each additional person, i.e., n*(n-1)/2 where n is the # of people.
