Severity and priority are 2 important parameters to triage and evaluate defects. Severity is the degree of impact a bug or defect has on the application under test while priority is the order in which the defect will be fixed. A critical or high severity means the failure resulting from the bug/defect has a larger impact, while a higher priority means the bug/defect will be prioritized for resolution. A quality engineer determines severity while a developer determines the priority; to balance both severity and priority to avoid conflicts, the same are reviewed in the defect triaging meeting which involves reviewing open bugs/defects and determining their order of resolution considering both these attributes along with other attributes such as team-capacity, environment availability, etc. To summarize the context, priority is associated with scheduling the issue while severity is related to functionality/operating procedures.
