Defect Probability

Defect Probability / Visibility: Definition, Categorization, Details:

Defect Probability (Defect Visibility or Bug Probability or Bug Visibility) indicates the likelihood of a user encountering the defect / bug.

  • High: Encountered by all or almost all the users of the feature
  • Medium: Encountered by about 50% of the users of the feature
  • Low: Encountered by very few or no users of the feature

Defect Probability can also be denoted in percentage (%).

The measure of Probability/Visibility is with respect to the usage of a feature and not the overall software. Hence, a bug in a rarely used feature can have a high probability if the bug is easily encountered by users of the feature. Similarly, a bug in a widely used feature can have a low probability if the users rarely detect it.

For more details on defects, see Defect.
