I get what you're trying to say but literally every department, bureau, and agency replaces leadership and huge numbers of staff when the White House changes parties. We can argue about whether that's a good thing, but those organizations do seem to weather the change and continue on with their core functions. The State Department is vastly more complex than a tech company yet manages to keep itself in order when one party is swept out and another rolls in. Part of their success is that continuity planning between administrations usually does rise above partisan rancor as staffers hand off their portfolios.
