Defect Severity in Software Testing
Can anyone point me to a definitive standard for defect severity levels in software testing? A search of ASQ turned up tens of thousands of results, Google supplied uncounted articles, tutorials, and consulting companies, and Wikipedia has a very short page with no sources cited at all.
Where do you turn when you categorize something as Severity One?
Thank you for any help you can provide,

If you are interested in searching through ASQ's published magazines and journals for information on your topic, you can do that here:

I searched the phrase "software defects" and received the following results:[1293861600000,1609394400000]&rpp=40
Perhaps some information found at the link above will assist you with your information need.

Here's a website that might be useful.
IEEE 1044 Classification of Software Anomalies has definitions and related guidance.  The standard was published in 2010 and I just noticed that it was withdrawn in 2020 (  The SEI also published a software quality measurement framework in 1992 (  The Personal Software Process also has relevant guidance.

There is no widely accepted norm for defect severity classification in software testing. However, Andersen's standard, can provide a useful starting point. Andersen is a software development and testing firm that has established three levels of severity: low, moderate, and high, which can be used as a benchmark.
