John Harkin is a professional in their field. Colleagues describe him as "I had the pleasure of working with John for 4 years. John was our group’s director, so he was 2 levels above me, but he was always approachable and knew how to inspire and motivate. John had some very tough challenges to deal with, both with internal politics and external customers, and he managed to steer through these minefields with great professionalism whilst still showing extra-ordinary leadership. John is an exceptional leader and I hope to get the opportunity to work with him again." and "John was initially a colleague (2 years) and later my manager at Nokia. I found him to be responsive, open, business minded and professional at all times. He is very adept at balancing corporate and customer requirements. I wish him all the best in his future endeavours."
