After months of conversations focusing on with Google Apps administrators and CIOs who had already migrated to the collaboration suite--and after many conversations with Dominion's C-level execs--Fuller gave a "final push presentation" to Dominion's execs, including the CEO, CFO and legal counsel, and ultimately won their approval.

"Their sale element was that this was a technological advancement for the company, Fuller says. "We didn't have a reputation for being on the leading edge of technology and this was an opportunity to do that, to be recognized by employees and do something that was ahead of the adoption point instead of lagging behind it."

Fuller's deployment of 4,200 Google Apps accounts--which began with a 150-person pilot group in June 2010--is scheduled for completion next month, and its reception has been positive, he says.

"The feedback we have is between 90 and 95 percent positive. We expected people to cling to Outlook more than they did--there are only 5 people still accessing Gmail through the Outlook client," Fuller says.
