"There are ample issues to consider, for example a team-based approach could raise the possibility of more affordable business models: Core content could be repurposed or remixed. The use of teams and pooled resources (even with other institutions or consortia) could help deliver the basic content and do much of the heavy lifting of teaching a given course.
Another big advantage to the team strategy is that having multiple team members fosters diverse perspectives. Decision making power shifts to a team of people, not just one person; this brings in additional and potentially fresh ideas. Teams may delegate the responsibility of tracking certain trends to member X or member Y; they might even add a new "hat" to the collective team membership if they want to employ a new technology that's been on their radar screen."
