What is Severity and Priority in Software Testing

Note:

Severity: This refers to the impact or seriousness of an issue or incident on the system or business operations. It typically involves assessing the extent of the problem and its potential consequences. Severity levels are usually categorized into several levels such as:
Critical: The issue causes complete failure of the system or significant loss of functionality, affecting a large portion of users or critical business operations.
Major: The issue causes severe impairment of system functionality, affecting a significant number of users or important business processes.
Minor: The issue causes minimal disruption to system functionality, affecting only a few users or non-critical business processes.
Priority: This refers to the level of urgency or importance assigned to addressing an issue or incident. It helps determine the order in which issues should be addressed, with higher priority issues typically being addressed before lower priority ones. Priority levels are often determined based on factors such as:
Impact: How much the issue affects users or business operations.
Urgency: How quickly the issue needs to be resolved.
Risk: The potential negative consequences of not addressing the issue promptly.
Priority levels are usually categorized into several levels such as:
High: The issue requires immediate attention and resolution as it has a significant impact on users or critical business operations.
Medium: The issue requires attention and resolution soon but does not have an immediate impact on users or critical business operations.
Low: The issue can be addressed at a later time as it has minimal impact on users or non-critical business operations.
