This document summarizes a presentation about E.ON Energy's data governance program. E.ON implemented a metadata management platform and data governance practices to address issues like limited data access, lack of a data catalog, and inefficient data usage. Initial results included defining data domains, connecting systems, training users, and standardizing reporting. The program aims to accelerate value from data, ensure compliance, demand trusted insights, and foster collaboration across the organization. Senior leaders must engage to support such initiatives, and building a data-driven culture is key to success.
