< The 2015 Tech 50: Racers to the Edge

The verdict is in on the Business Operations and Information Technology Transformation program that State Street Corp. began in 2010: more than $625 million in annualized pretax savings, fully realized this year. That is how it was reported to shareholders, anyway. To executive vice president and chief information officer Christopher Perretta, the official completion of the IT transformation, a bold and leading-edge commitment to cloud computing at the time of the project’s launch, is but “an opening gambit that whetted our appetite for more and better things. We are continuing on toward the digital enterprise.” Now it gets interesting, the 57-year-old says, because the process of exploring and mining the technology’s full potential will be ongoing and iterative. Coming from an electrical engineering background — bachelor’s degree from Johns Hopkins University, master’s from Syracuse University — and having been exposed to industrial processes while a financial executive with General Electric Co. and a consultant with Andersen Consulting, Perretta views big-data opportunities through a manufacturing lens. “Like moving steel through a factory, one piece of data links to another, like in an assembly line,” he explains. “Getting it to flow as seamlessly as possible leads to more insight.” Unleashing the assembled computing power, which can perform in minutes or hours what used to take days or weeks, “we can interrogate our systems, leading to increased transparency, better interactions with clients and more-efficient supply chains,” he adds. At State Street since 2007 and overseeing more than 5,000 employees and contractors, Perretta says the “fully automated factory” also must stress reliability. This increases demand on the “factory floor” for “operations research types who pull systems apart and engineer them to improve performance.”
