    - All software defects are not caused by coding errors.

    - One common source of expensive defect is requirement gaps.

    - Not all defects will result in failures. For example, defects in dead code will never result in failures.

    - A defect can turn into a failure when the environment is changed.

    - A single defect may result in a wide range of failure symptoms.

    - Following are the situations where the defects will arise:

      - When system is being used in a wrong way.
      - When program is coded wrongly.
      - Incorrect setup of testing environment.
      - Lack of system knowledge.
