"It's an honor for State Street to be named to this prestigious ranking for the third consecutive year by a premier technology industry publication and, more importantly, by our own IT staff," said Joseph Antonellis, executive vice president and chief information officer for State Street. "This recognition underscores our unique ability to create innovative technology solutions for our customers while fostering a workplace environment characterized by professional education and development." Since 1994, the Best Places to Work in IT feature has ranked the top 100 work environments for technology professionals based on a comprehensive questionnaire regarding company offerings in categories such as benefits, diversity, career development, training, and retention. In addition, this year Computerworld surveyed more than 27,000 IT workers for the list, and their responses factored heavily in determining the rankings. "In recent years, IT executives have been faced with a number of issues that have made their work environments increasingly challenging," said Don Tennant, editor in chief for Computerworld. "Those represented in the 2006 Best Places to Work program have cultivated an environment that recognizes the value of IT workers within the organization." The Best Places to Work feature appears in the June 19 issue of Computerworld. For the complete ranking, please visit www.computerworld.com/2006bestplaces.
