A data inventory is a good starting point to understand the scope of privacy program needs, as it provides a comprehensive overview of what personal data is collected, processed, stored, shared, and disposed of by the organization. A data inventory can help identify the legal obligations, risks, and gaps in the privacy program, as well as the opportunities for improvement and optimization. The other options are also important components of a privacy program, but they are more effective when based on a data inventory.
