It shows the fundamental differences in the work a manager and a software engineer does. The open communication will make it easier for the manager to load-off work, to stay in the loop, to check on their employees "subtly" and writing all those project plans and reports does not take the same amount of "being in the zone" as software engineering does. So if the manager works better with more people around them and everybody knows how important communication is since they keep drilling that into managers these days - well of course your manager is going to assume that putting 5 times as many coders into one room is going to give them 5 times the results plus even more since we all know in a team 1 + 1 = 3, right??? The sad thing is, it is obvious that to this day most managers have no clue how software engineering and any other kind of "knowledge work" (I hate that term) is fundamentally different from Ford's ideas of mass production.
