Interview Questions

Severity level:

Why are there Bugs in Software?

(Continued from previous question...)

Severity level:

The degree of impact the issue or problem has on the project. Severity 1 usually means the highest level requiring immediate attention. Severity 5 usually represents a documentation defect of minimal impact.


  • Critical: the software will not run
  • High: unexpected fatal errors (includes crashes and data corruption)
  • Medium: a feature is malfunctioning
  • Low: a cosmetic issue

  1. Bug causes system crash or data loss.
  2. Bug causes major functionality or other severe problems; product crashes in obscure cases.
  3. Bug causes minor functionality problems, may affect "fit anf finish".
  4. Bug contains typos, unclear wording or error messages in low visibility fields.

  • High: A major issue where a large piece of functionality or major system component is completely broken. There is no workaround and testing cannot continue.
  • Medium: A major issue where a large piece of functionality or major system component is not working properly. There is a workaround, however, and testing can continue.
  • Low: A minor issue that imposes some loss of functionality, but for which there is an acceptable and easily reproducible workaround. Testing can proceed without interruption.
