"I think marketers are responsible for understanding consumer needs. And if you develop a product, it's always important to understand consumer needs from the beginning, not to wait until it's done and then say, okay, now deal with it and try to put some plasters on it. So one is, I think for me, deeply understanding consumer need is understanding the consumer perspective in a deep way, understanding how to gain insights, kinds of research and understanding how to translate those insights to that particular product."
