What is the relationship between Business Continuity and Risk Management?
The relationship between Business Continuity and Risk Management depends on the organization. In most cases, Business Continuity is a sub-domain of Risk Management.
If there is an existing Enterprise Risk Management framework in the organization, can you use that in your Business Continuity Planning? Or, should you create a new Risk Register and new Risk Assessments for each department inside the Business Continuity Plan?
You should refer to your organizational Risk Register as a starting point. However, some Business Continuity Plans may contain lower level risks that are important to the department but not significant to the organization as a whole
Risk Management is focused on the mitigation of issues and Business Continuity is more concerned about a worst case scenario action plan.
