I wonder if plagiarism is the reason for the increased number of group projects in university courses? At least, they seem to be a lot more common now than they used to be. It would be harder to plagiarise group work than individual work - everyone would have to agree to it.
But all I hear about group projects is complaints about the group getting one member to do all the work for them.
Which would equip N-1 members only for management, not for actual work
