“Berkeley provided high quality end-to-end delivery. I didn’t need to babysit the engagement, yet I felt sufficiently in control of the overall direction. They very quickly tuned-in to the corporate culture and tailored the product in a way that gave it the best chance of gaining traction in the business.”

"They worked ‘‘ seamlessly alongside us providing leadership, drive and integration expertise while ensuring that we still felt in overall control. From the start, there was a strong emphasis on embedding ownership for the new operating model within the GTR team. It didn’t feel like working with consultants."
