What's the difference between the "Content Owner" and "Assigned" Team Members?

Answer:

We would define the Content Owner as the individual who is ultimately responsible for the completion of a content item. The other team members who are 'Assigned' to a content item are typically people who need to be kept informed of the progress of the project (they'll receive activity notifications), or who handle individual production tasks (i.e. copywriting, editing, creating a graphic, reviews, approvals, etc.).
