Designsafe analysis of the product.
Rating of severity and probability are based on a 1-5 scale with 1 being very low and 5 standing for very high. The risk level is the product of severity and probability. The Risk level definition is shown as follows:
Table XII-2. Risk level definition
Risk level >11 is considered as: need for mitigation.
Risk level >5 but <=11 is considered as: acceptable, but could be better.
Risk level <=5 is considered as: acceptable.
