Il numero di priorità del rischio (RPN) è una misura quantitativa utilizzata in Analisi FMEA to prioritize risks. It is calculated as the product of three ranked factors: Severity (S), Occurrence (O), and Detection (D). The formula is [latex]RPN = S times O times D[/latex]. Each factor is typically rated on a scale from 1 to 10, allowing squadre to focus on the highest-scoring risks first.
