Here is the text right out of the March 12th e-mail that announced the change:
Rob will take on responsibility for managing our processes and best practices within the Group. He will continue to lead our Database design discipline, but will also take on management for the Corillian [Professional Services] Architects. Michael Hallabrin, Tim Sarna, and Rocco Martin will report in to Rob as part of the CO-L Solutions Architecture team.I am really excited about this new role. Michael, Tim, and Rocco are a bunch of really smart guys, and I am enjoying working more closely with them.
