What is a major concern when data is processed in an unregulated manner by end-user applications?

When data is processed in an unregulated manner by end-user applications, the lack of independent reviews and checks is a significant concern because it can lead to various issues related to data quality, security, and compliance. Without independent oversight, there is no mechanism in place to ensure that data handling follows established guidelines or best practices. This can result in errors, inaccuracies, and potential data breaches.

Independent reviews and checks are important for validating the integrity and correctness of data processing activities. They help identify any risks that may arise from uncontrolled changes, unverified algorithms, or insufficient safeguards. An absence of such reviews can compromise data governance and accountability, leading to serious implications for business operations, regulatory compliance, and the trust of stakeholders.

While the other options raise valid points, they do not address the critical role of independent reviews and checks in ensuring proper data management and governance. Therefore, prioritizing independent scrutiny is vital to maintain data integrity and protect the organization from potential risks.
