What is Defect Priority?

Defect Priority signifies how important & urgently it is to fix this defect. In other words Priority means how fast it has to be fixed. The Defect priority status is set by the project manager based on the customer requirements & based on Project Priorities the product fixes are done. Priority is related to scheduling to resolve the problem. It is a pointer towards the importance of the bug & if High priority is mentioned then the developer has to fix it at the earliest. It is related to technical aspect of the product. It reflects on how bad the bug is for the system and also largely related to Business or Marketing aspect.

Defect Priority is classified into the following categories:
  • Show stopper:  This needs to be fixed right now, everything else can wait, the build cannot be released with this defect
  • Urgent: Needs to be fixed before any other high, medium or low defect should be fixed
  • High: Should be fixed as early as possible
  • Medium: May be fixed after the release / in the next release.
  • Low: Fixing can be deferred until all other priority defects are fixed

It is also represented as P1 for Show stopper, P2 for Urgent Priority, P3 for High Priority, P4 for Medium and P5 for Low Priority.
