What is severity and priority? How do they differ? Provide an example of a defect with low priority and high severity.

Severity — this is the degree of impact of a defect on the system's operation. It indicates how critical an error is for the product's functionality.

Priority — this is the degree of urgency in fixing the defect, determined by business goals and release plans.

Differences:

• Severity — a technical assessment of the error's impact.
• Priority — a business assessment of the importance and order of fixing.

An example of a defect with low priority and high severity:

An error that causes a failure in a non-core function used rarely, for example, a failure in the report generation module, which is only used at the end of the month. The severity is high because the function does not work, but the priority is low because the fix can be postponed until the next release, as it does not affect core business processes.
