Capital One also has conference rooms, which need to be reserved in advance, and huddle rooms -- small, unreserved conference rooms designed for groups of four or fewer who need a private work space.

The company has wireless capabilities throughout its campuses to support its FOW program, which is continuing to expand throughout the company's workforce.

IT was already supporting mobile technologies before the FOW program started, says Lee Congdon, managing vice president of corporate technology. But it had to step up its distribution of cell phones to employees and continue to focus on security, which becomes more complex in a mobile environment. And because IT needed to work more frequently with remote employees, it had to expand services such as remote diagnostics offered through its help desk.

Now the company is moving to VOIP, which will allow even greater ease of movement, Congdon says.

The FOW rollout did come with additional expenditures, such as the costs of cell phones and docking stations for mobile devices. Capital One officials won't disclose investment costs, but Congdon says the expenses were more than offset by savings in work space on the real estate side. Moreover, he says, employees are happier, and productivity is up.
