Which of the following is essential for effective control of changes within the organization?

A systematic approach to planning and management is essential for effective control of changes within an organization because it provides a structured framework for implementing modifications in a controlled and deliberate manner. This approach ensures that all aspects of the change process are considered, including risk assessment, resource allocation, stakeholder communication, and compliance with established procedures and policies.

By employing a systematic approach, organizations can minimize disruptions, ensure consistency, and better manage the potential impacts of changes. It allows for thorough documentation and evaluation of changes, which is crucial for maintaining compliance with standards such as ISO 27001 that emphasize risk management and information security.

Additionally, a systematic method facilitates continuous improvement by enabling organizations to learn from previous changes, refine their processes, and make informed decisions about future adjustments. Overall, this proactive management of change fosters a culture of accountability and enhances the organization's resilience in adapting to evolving circumstances.
