"We've realized that one of the greatest services that Clifford Chance can bring to its clients is the strength and depth of its global network of legal experts," said Charles Doyle, Global Head of Business Development at Clifford Chance. "As such, we have invested in InterAction, which is capable of supporting our global client service initiatives."

Clifford Chance, widely considered the world's largest law firm, first implemented InterAction on a limited basis in 1999 to centrally track and manage strategic relationships, matter details and other information critical to achieving strategic client development objectives. The success of that initiative gave the firm confidence in the soundness of investing in a global InterAction initiative.

"Clifford Chance has an outstanding reputation in the marketplace for their technical insight and sophistication, and is renowned for investing in best-in-class solutions," said John McDonnell, vice president and general manager for InterAction.
