Which of the following would be the BEST time to create a data governance plan...

In AI development, " Privacy by Design " and " Governance by Design " are fundamental principles. The data governance plan should be created " As part of the initial design " phase. This ensures that the requirements for data quality, lineage, labeling, and privacy are integrated into the architecture from the beginning. According to the AAIA™ framework, attempting to retrofit governance during the testing (Option A) or production (Option B) phases is often impossible or cost-prohibitive, as the data may have already been corrupted or collected in a non-compliant manner. Planning at the design stage mitigates the risk of building on a flawed foundation.
