The percentage of projects introduced into production without high-risk issues is the most important measure of the effectiveness of risk management in project implementation, as it reflects the ability of risk management to ensure that the project deliverables meet the quality,functionality, and security requirements, and do not introduce unacceptable risks to the organization. The percentage of projects having the risk register updated regularly, having key risk indicators (KRIs) established to measure risk, or having an action plan to remediate overdue issues are not the most important measures, as they are more related to the process, performance, or compliance of risk management, rather than the outcome or value of risk management. References = CRISC Review Manual, 7th Edition, page 110.
