Conducting root cause analyses for risk events is the first recommendation that a risk practitioner should make when an increasing trend of risk events and subsequent losses has been identified, as this helps to identify the underlying causes and sources of the risk events, and to determine the appropriate actions to address them.
Root cause analysis is a systematic process of collecting and analyzing data, finding the root causes, and implementing solutions to prevent recurrence or reduce the impact of the risk events. Educating personnel on risk mitigation strategies, integrating the risk event and incident management processes, and implementing controls to prevent future risk events are not the first recommendations, but rather the possible outcomes or actions of conducting root cause analyses for risk events.
