While RBS's commitment to Facebook at Work represents a new high-water mark for the platform's adoption rate, it also reinforces Facebook's ability to convince businesses in highly regulated industries to consider the platform as their next tool for collaboration and communication. Facebook at Work may not necessarily replace all of RBS's preferred communication tools, according to Hanley, but it could improve upon the ones that are already in use.
"We don't see Facebook at Work ever replacing any of our current communication tools," Hanley says. "But we do think that email use will start to dampen down with its introduction, as people use Facebook at Work as another of way of talking and working with each other."
Though some CIOs expressed concern about Facebook at Work security and regulatory compliance, relative few have had the opportunity to actually try the product. RBS's company-wide deployment could ultimately help Facebook prove that its social network for business is suitable for use by large enterprises, and downplay the idea that it's designed for smaller organizations.
