Which of the following actions represents the most effective and compliant approach for the team to adopt immediately?

Accepted Answer

Proactively engage legal and compliance teams to fully understand the new regulation's specific requirements, conduct a thorough impact assessment on the current data processing pipeline and models, and immediately begin developing a revised strategy that integrates the new mandates, potentially exploring anonymization techniques and adjusting data storage protocols.

Question 15

A data analytics team has completed a project analyzing customer feedback to identify areas for product enhancement. The data collected included customer names, email addresses, and verbatim feedback. Following the successful completion of the project, the team lead proposes retaining the entire dataset, including personal identifiers, for potential future use in targeted marketing campaigns, which were not part of the original project scope. What is the most ethically sound and legally compliant approach to managing this data moving forward, considering principles of data minimization and purpose limitation?

Accepted Answer

Anonymize or securely delete the customer feedback data, as its original purpose has been fulfilled and retention for unrelated future marketing without new consent is not permissible.

Question 16

A data analytics firm, \'Insight Analytics\', is engaged by a retail conglomerate to optimize their supply chain logistics. Midway through the project, the client announces a strategic shift to prioritize sustainability reporting, demanding a significant alteration in the data collection and analysis focus.
