The numerical formulas were updated to incorporate the new metrics while retaining the existing scoring range of 0-10. Textual severity ratings of None (0), Low (0.1-3.9), Medium (4.0-6.9), High (7.0-8.9), and Critical (9.0-10.0) [13] were defined, similar to the categories NVD defined for CVSSv2 that were not part of that standard.

The Emergency Severity Index (ESI) is a five-level emergency department triage algorithm, initially developed in 1998 by emergency physicians Richard Wurez and David Eitel. [1] It was previously maintained by the Agency for Healthcare Research and Quality (AHRQ) but is currently maintained by the Emergency Nurses Association (ENA). Five-level ...
RAC CRTA–FMECA and MIL–HDBK–338 both identify Risk Priority Number (RPN) calculation as an alternate method to criticality analysis. The RPN is a result of a multiplication of detectability (D) x severity (S) x occurrence (O). With each on a scale from 1 to 10, the highest RPN is 10x10x10 = 1000.
Risk is the lack of certainty about the outcome of making a particular choice. Statistically, the level of downside risk can be calculated as the product of the probability that harm occurs (e.g., that an accident happens) multiplied by the severity of that harm (i.e., the average amount of harm or more conservatively the maximum credible amount of harm).
The Revised Trauma Score is made up of three categories: Glasgow Coma Scale, systolic blood pressure, and respiratory rate. The score range is 0–12. In START triage, a patient with an RTS score of 12 is labeled delayed, 11 is urgent, and 3–10 is immediate.
The pandemic severity index (PSI) was a proposed classification scale for reporting the severity of influenza pandemics in the United States. The PSI was accompanied by a set of guidelines intended to help communicate appropriate actions for communities to follow in potential pandemic situations. [ 1 ]
In operations research and engineering, a criticality matrix is a representation (often graphical) of failure modes along with their probabilities and severities.. Severity may be classified in four categories, with Level I as most severe or "catastrophic"; Level II for "critical"; Level III for "marginal"; and Level IV for "minor".
It is defined as the product of severity, likelihood, and class. Defects are different from user stories , and therefore the priority (severity) should be calculated as follows. Severity/impact
