What makes Customer Data Science work?

“I believe passionately in an unrelenting focus on the customer and our clients, and that success is best gained through a deep understanding of both. It is only when we achieve this level of understanding, from the insights we see in customer data, that we know what our clients need to do differently for customers and how they can get it done.”
