Defect Levels

The five recommended Defect Levels are as follows:

1.   Critical

2.   Major

3.   Average

4.   Minor

5.   Exception

 

1. Critical - The defect results in a ‘show stopping’ failure of the complete software system, of a subsystem, or of a software unit (program or module) within the system.

2. Major - The defect results in the failure of the complete software system, of a subsystem, or of a software unit (program or module) within the system. There is no way to make the failed component(s) work, however testing can continue in other areas.

3. Average - The defect does not result in a complete failure, but causes the system to produce incorrect, incomplete, or inconsistent results, or the defect impairs the systems usability, but some workaround exists.

4. Minor - The defect does not cause a failure, does not impair usability, and the desired processing results are easily obtained by working around the defect. However, a management decision must be made to assess the work around solution.

5. Exception - The defect is the result of non-conformance to a standard, is related to the aesthetics of the system, or is a request for an enhancement. Defects at this level may be deferred.
