The problem requires creative thinking on the part of CIOs who have already taken pains to reduce IT costs in response to financial pressures from CEOs and chief financial officers. Many IT chiefs have plucked the so-called low-hanging fruit such as hardware consolidation and standardization and have renegotiated software licensing agreements, making it increasingly difficult to find new avenues for operational savings. But senior business leaders continue to yell "Cut!"

"I look at maintenance as a bucket that's swashing around with lots of holes in it," says Anthony Abbattista, vice president of enterprise technology strategy and planning at Allstate Insurance Co. in Northbrook, Ill. The idea, says Abbattista, is to determine how much money is leaking through those holes and figure out a way to plug them up.

One technique that world-class IT shops have been using to control IT operational costs is to set up centers of excellence where IT workers are grouped by areas of expertise such as data center management, Java or .Net development, says Anton Kritzinger, a consultant at Compass North America in Toronto. "Rather than having a number of groups that are good at what they do, you end up with one that is very good at what they do," says Kritzinger. "The payback is significant."

Allstate has done this successfully. "The first thing we did was look for duplicative activities where different organizations were doing similar things," says Abbattista. Beginning in February 2003, the company's IT department made structural changes to create technology groups that handled common activities across the organization, he says.

Around the same time, Allstate also began conducting "white-collar timekeeping" to help Abbattista and other IT managers track which projects IT staffers were working on at any given time. Through these efforts, which include benchmarking its IT skills costs, Allstate has shifted the percentage of annual IT spending in operations and maintenance from more than 70 percent in 2003 to between 30 percent and 35 percent today, says Abbattista. Each year since 2003, Allstate has reinvested "a few hundred thousand dollars" in savings generated by the centers of excellence toward discretionary IT spending, he adds.
