In which scenario would you NOT need to perform a policy review?

A policy review is generally performed to ensure that existing procedures and guidelines remain relevant and effective in light of new situations or requirements. In the case of understanding customer preferences, this activity is more about gathering insights and feedback to inform services and interactions rather than re-evaluating the policies governing email security or data protection practices.

Policies typically need to be reviewed in response to significant changes, such as when new users are onboarded and require specific guidelines, when there are regulatory changes that necessitate updates to compliance measures, or during routine system checks that might uncover gaps or improvements needed in existing policies. Understanding customer preferences does not inherently trigger the need for a policy review, as it focuses on adapting to user needs rather than adjusting policy frameworks. Thus, it's correct that a policy review would not be required in this scenario.
