: A standard mechanism to rate each failure mode on a scale of 1 to 10 based on: Severity (S) : How serious the consequences are.

: The likelihood that current controls will catch the failure before it reaching the customer. Prioritization Engine : Risk Priority Number (RPN) : Automatically calculated as to provide a preliminary priority list.

: The specific way a system or component fails to meet its intended function (e.g., fracture, electrical short).

: The impact of the failure on the end user or system (e.g., overheating, abnormal shutdown).

: The frequency or likelihood of the cause occurring.
