8 text Risk Analysis Approaches Risk Matrixes Probability vs. Severity = High, Medium, or Low Risk Definition & Categorization Level I = Level II = Level III = Pre-Defined Question & Decision Tree If then, else Yes Occurrence Medium Risk Low Risk Do Control Measure(s) exist for the identified hazard? Yes No Does this step eliminate or reduce the likely occurrence of a hazard to an acceptable level? No Could the identified hazard(s) occur in excess of acceptable level(s) or could it increase to an unacceptable level(s)? Yes Will a subsequent step eliminate the identified hazard(s) or reduce its likely occurrence to an acceptable level? High Risk Severity Is control at this step necessary for Intended Use (SQUIPP)? Yes No Not A CCP Yes Modify Step, or Product No Critical Control Point Page 8

9 Risk Assessment Tools FMEA - Failure Modes Effects Analysis FMECA - Failure Modes Effects & Criticality Analysis FTA - Fault Tree Analysis HACCP - Hazard Analysis Critical Control Points And Combination Methods Tools & Approaches Page 9

10 Combination Methods Overview Key Questions to Ask & Understand What is the Risk Focus? What are the Risk Requirements? What are the Risk Metrics to be quantified & Measured? What is the Outcome of the Exposure? As well as What is it you need? How do you plan to do it? What is the ultimate outcome? What are the challenges?
