The effectiveness of an AI-driven business process-such as categorizing customers for promotional campaigns-depends on how well it supports defined business objectives. The AAIA™ Study Guide recommends validating that AI methodology aligns with intended outcomes as part of performance auditing. "Effectiveness is best measured by assessing whether the AI logic contributes meaningfully to business goals. Output alignment with organizational KPIs or campaign strategies provides clear evidence of functional success." Options A and D support operational resilience and quality assurance. Option C is a privacy technique, not directly tied to effectiveness validation. Thus, B is correct.
