Mob programming because they don't trust the individual developers to deliver by themselves, mob programming because no one has a clue there and they hope there is wisdom in the crowd, and mob programming because they had nothing else to do.
Yes, I upvoted because you mentioned that one of the concept is the wisdom, but I for one am aware of the other concept called 'socialism': you have to be sure that each member of the team passed the entry exam, and you have to be sure that none of the team members become lazy and relies on others to lift the heavy burden, because if everyone avoids the heavy burden, then the 'socialism' collapses.
