Requiring a risk assessment with change requests is the most effective way to integrate business risk management with IT operations because it ensures that any changes to the IT environment are aligned with the business objectives and risk appetite.

This way, the IT operations can support the business goals and mitigate the IT risks in a proactive and consistent manner.
