What is the purpose of "Change Control" in ITIL 4?

The purpose of "Change Control" in ITIL 4 is to ensure that changes to IT services or products are made with proper assessment and authorization. This practice is crucial because it helps manage risk and minimizes the potential impact that changes can have on existing services. By following a structured approach to evaluate and authorize changes, organizations can ensure that all potential impacts and risks are carefully considered before a change is implemented. This not only helps maintain service quality but also enhances the organization's ability to adapt to new requirements or technologies reliably.

Furthermore, Change Control supports the overall framework of ITIL 4 by promoting transparency and accountability in change management processes, thereby fostering trust among stakeholders. It highlights the importance of documenting the rationale behind decisions and maintaining a record of changes for future reference, which is vital for continual improvement.
