Deborah kops joins us and shares her views on GBS: "It's a dynamic business model. It is not one rigid business model. To be very honest, to some extent we've promulgated that through the consultancy class in this industry, some of those guys are some of my best friends. But a business services platform is whatever you can do at any given time, given your leadership, given a range of external and internal factors. So GBS as a concept I don't buy."
