Donna Seymour, CIO of the DOT's Maritime Administration (MARAD), said a July move of the agency's Washington headquarters is to blame for the reluctance to deploy Microsoft's new software. "It has less to do with technical concerns about Microsoft and more to do with the fact that with our July move, our plates are totally full and we can't take another thing on right now," she said in an interview Monday after a speech at the Computerworld Premier 100 IT Leaders conference in Palm Desert, Calif.

MARAD has already begun testing Vista and IE 7, according to Seymour. That testing, however, may take time because MARAD relies extensively on old, custom applications that will require long evaluation on Vista. She has not yet set an upgrade timetable, but if or when she does, Seymour said, she can add Vista and Office without spending additional money; MARAD has a Software Assurance contract with Microsoft.

Even if her department doesn't widely deploy Vista and Office 2007 until early 2009, "we would be middle of the pack among private corporations and somewhat ahead of most government agencies," Seymour claimed.

In late January, Daniel Mintz, the DOT's CIO, issued an internal memo slapping a moratorium on upgrading desktops and laptops to Vista, the Office 2007 business suite and IE7, the revamped browser Microsoft released last October. "This establishes an indefinite moratorium until further notice on desktop/laptop computer software upgrades to Microsoft Vista, Office 2007 and Internet Explorer version 7," the DOT memo read. "Microsoft Vista, Office 2007 and Internet Explorer may be acquired for testing purposes only."

The memo, which the DOT posted publicly on Jan. 22, went on to say that a follow-up in six months would lay out the agency's 2008 migration road map, leaving the door open to a policy change then. A similar ban will be put into place separately by the Federal Aviation Administration (FAA), which is part of the DOT, the memo also said.
