A data protection impact assessment (DPIA) is designed to identify and mitigate risks to data privacy. The CGEIT Review Manual 8th Edition states that the primary objective of a DPIA is to analyze how business processes affect data privacy, particularly for personal data.

Extract from CGEIT Review Manual 8th Edition (Domain 3: Risk Optimization):"The primary objective of a data protection impact assessment is to identify and analyze how business processes, systems, or projects may impact the privacy of personal data. This helps ensure compliance with data protection regulations and mitigates privacy risks." (Approximate reference: Domain 3, Section on Data Privacy and Compliance)

Identifying and analyzing how data privacy might be affected by business processes (option A) is the core purpose of a DPIA, aligning with regulatory requirements like GDPR.

Why not the other options?

B. To evaluate the quality and integrity of personal data stored in an enterprise: Data quality is a separate concern, not the focus of a DPIA.

C. To estimate the value created by personal data as it progresses through its life cycle: Value estimation is a business analysis, not a DPIA objective.

D. To ensure key business processes and related data interfaces are documented: Documentation may be a byproduct, but it is not the primary objective.
