DEFECT PROBABILITY, also known as 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 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 that particular feature. Similarly, a bug in a widely used feature can have a low probability if the users rarely detect it even while using that particular feature.
