To illustrate an example...
Problem Area: Lack of effective data governance which is preventing the development of analytics reporting.
Problem Description: No one knows who owns which data and arguments are frequent. IT have created data models related to technology systems as opposed to the way in which the business actually works. No one from the business understands these.
Solution: Design a single diagram depicting how data flows across the organisation that every leader can understand. Once accepted by leadership, overlay org chart against diagram to begin assigning data ownership. Where overlaps exist, use this diagram as an anchor point to model at a deeper level. Rinse and repeat with affected management.
