ELI5: Explain Like I'm 5

Parallel individuation system

Parallel individuation system is like a chore chart for adults. It is a way for adults to make sure that everyone in a group is taking care of the same amount of tasks or responsibilities. Everyone in the group agrees on a list of tasks that need to be done, such as cleaning or taking care of the bills. Each person then takes responsibility for a certain number of those tasks. That way, everyone is helping out and doing their fair share.
