Some places use eg P1 P2 P3 instead of SEV1 SEV2 SEV3 the classification can be in terms of impact to the business. E.g. "P1" could be reserved for issues severe enough to prevent the business from functioning as a business. (E.g. the bank that cannot process customer transactions, the cdn that cannot distribute content) P3 might mean some features of a service are broken and 1% of your customers are pissed but there is a workaround available or the features aren't really critical
