Yes, and if different parts of an organization don't communicate, then the systems they develop / procure will often be stovepiped.
I have seen this in a UK civil service acquisition organisation, that even lacked consistent shared engineering guidance for the different teams. They did at least approximately follow the same acquisition guidance so there were commonalities with how they approached industry and managed the bidding process.
