Mapping data flows involves creating visual representations, often in the form of flowcharts, to illustrate the pathways and processes data undergoes. This helps in understanding the current state and identifying areas for improvement. Key steps include: 1. Identify Data Sources: List all points where data is generated. 2. Document Processes: Outline how data is processed and by whom. 3. Map Storage Locations: Note where data is stored at various stages. 4. Trace Distribution Channels: Identify how data is shared or transferred. 5. Review and Validate: Confirm the accuracy of the flow with all stakeholders.
