  • 14-2aHave you prepared measures to track the data flow and lineage?
    • There may be AI system changes, such as model expansion or redesigning due to changes in data. Thus, continuously tracking the flow and lineage of data that induce changes in the system is crucial.

    • Data flow and lineage can be tracked using backward, forward, or end-to-end approaches, and the following are matters to consider for tracking.
    - Would it be useful to form a data policy team to manage the tracking of data flow and lineage?
    - Will you record and maintain the metadata to track data flow and lineage?
    - Would it be useful to implement data loading, mapping, management, and visualized reporting functions to track data flow and lineage?
    - Would it be useful to implement a feature repository function that saves and shares the feature value of the model in the AI development process?
    - Can the data be backtracked to the provenance?
