Just a point of clarification, for future reference:
The linked example specifically ranked severity classifications using the terminology "injury requires professional medical attention" with no particular identification of any harms. I feel that this was a very poor choice for this specific example, given that the harms were not identified and the identified person responsible (in the linked example) for making the assessment was a design engineer. Each of us may personally know individuals who fall along different points of the spectrum between hypochondria and a stubborn refusal to seek medical treatment!
In my general experience, 5-point scales for severity rankings are often commensurate with a general concept of "how much medical attention", but that specific terminology can be problematic. I am much more comfortable with having a general list of specific harms, each with an identified Severity rating. If possible, such a "master harms list" ought to be vetted by an accredited medical professional familiar with the identified harms; if such a professional isn't familiar with the application of 14971, they may need to be informed about the theory of separation of S from P1 and P2. Strictly speaking 14971 doesn't require such a person, but it doesn't require that electrical engineers know how to use a digital multimeter either.
