Technical innovation is a top priority at this payroll and tax-filing processing service in Roseland, N.J. In 2013, ADP challenged IT staffers to contribute product enhancement ideas through its Amplifier crowdsourcing platform, eventually collecting 400 ideas, 10,300 votes and 6,500 comments. Prizes were awarded to the top ideas and collaborators, and the winners presented their ideas at an IT leadership meeting in Washington, D.C. To attract and retain new design and technical talent, the company has expanded its successful Innovation Labs to a new facility in New York's Silicon Alley.
