This third instalment digs deeper into when and why data stopped belonging to the business, and how that loss of ownership created the "data priesthood" so many organisations now depend on. Reclaiming value from data doesn't start with new tools; it starts with returning ownership, context, and trust to business domains. Drawing from research by Gartner, McKinsey, Forrester, Deloitte, AWS, and BARC Germany, this piece explores how the next era of data and AI, will be defined not by centralisation, but by empowerment.
