The operations further include providing, to the user, a commitment communication advising the user that the system will be dedicated to participating regularly, actively, and collaboratively as a team member. The operations also include receiving, from the user, an agreement communication to participate as a member of the collaborative ACC team. And the operations include forming, responsive to receiving the agreement communication, the collaborative ACC team including the user and team-oriented ACC system.
