Time Warner Cable's Peter SternTime Warner Cable revamped its senior management team by giving additional responsibilities to Peter Stern. Stern, who is the cable operator’s executive vice president and chief strategy officer, has taken on the roles of chief people officer and leader of corporate development.

Stern took over the human resources functions from Tom Matthews, who is leaving the company for personal reasons, and corporate development from Carl Rossetti, who will retire at the end of this year.

Stern continues to report to Time Warner Cable Chairman and CEO Glenn Britt and will retain responsibility for shaping the company’s strategy and oversight of its residential broadband and phone businesses.

Stern is now tasked with all corporate human resources functions, including organization design, talent planning and acquisition, people development, compensation and benefits, and HR shared services.

His corporate development responsibilities include overseeing Time Warner Cable’s Intelligent Home security business, wireless initiatives such as community Wi-Fi and the company’s partnership with Verizon Wireless, as well as other new businesses.

“Time Warner Cable’s people are the heart of our strategy and the key to unlocking new opportunities,” Britt said. ”Strategy, people and corporate development are inextricably linked, and I am pleased to bring these functions together under Peter’s leadership. I look forward to working with him to bring an even more strategic approach to the development and management of our 51,000 people.”

Stern joined Time Warner Cable more than a decade ago and has served in a number of strategy and product roles at both Time Warner Cable and its former parent, Time Warner Inc. He played an integral role in developing the company’s mission, values and strategy and led industry-shaping product initiatives such as Start Over, TV Everywhere and Signature Home.

Before joining Time Warner, Stern was an associate principal at McKinsey & Co. He has a J.D. from Yale Law School and an A.B. from Harvard College.

In announcing the management change, Britt thanked Mathews for his service to Time Warner Cable, which he joined in 2002.

“Tom is an enthusiastic, passionate leader. In his years at the company, he has shaped our HR function during times of significant change, including our separation from Time Warner and numerous acquisitions,” Britt said. “I speak for all of my colleagues in thanking him and wishing him well.”
