Software Error Classification


The idea is that only fields that are being actively used should be present. On some projects, more resources may be spent on testing than in developing the program. For example, when a programmer writes (pseudocode) LET REAL_VALUE PI = "THREE AND A BIT", although this may be syntactically correct, the code fails a type check. Vol. 4, Issue 3, pp.20–24. this content

Please help improve this article by adding citations to reliable sources. Instead of lingering on how failure analysis defines the failure modes, let's focus on the prioritization aspect.

Priority is generally a customer or user-defined element that addresses how quickly they need a resolution of some kind. You don't want anything too complicated such that it can't be understood, and in line with Orthogonal Defect Classification, don't want defects to be able to be put into multiple categories. A program that contains a large number of bugs, and/or bugs that seriously interfere with its functionality, is said to be buggy (defective). Defect Releases that emphasize bug fixes are known as maintenance releases.

Trying to find the perfect label for things that are defects, versus bugs, versus failures, doesn't get me further in finding the solution. For example, a crash (high severity) that happens only rarely may be low priority. Using an otherwise valid instruction on the wrong data type (see packed decimal/binary coded decimal). my review here Sounds like it almost fits in support-request. –Michael Urman Feb 16 '11 at 14:27 @Michael I forgot to add that one.
