A test and change management system is important for the following reasons, even though it is not explicitly required under GDPR:
Ensuring Data Security: It ensures the integrity, availability, and confidentiality of data by controlling and securely implementing changes in systems and processes.
Avoiding Unintended Consequences: It helps prevent unintended negative impacts on data security by thoroughly testing and evaluating changes.
Proactive Risk Mitigation: Implementing such processes demonstrates to authorities and partners that the organization is proactively minimizing data protection risks.
Enhancing Compliance: It strengthens data protection compliance by ensuring that all changes meet data protection requirements and are carefully monitored.
Building Trust: It builds trust with customers and business partners by demonstrating that the organization is serious and systematic about protecting data privacy.
