Defect Priority Categorization

As the priority refers to the sequencing or order, it tells the order of defect resolution. Priority sequencing is categorize on the following basis –

1. P1/Critical
2. P2/High
3. P3/Medium
4. P4/Low

P1/Critical –

• The defect which needs to fix immediately
• P1 is marked when the affected area or feature stopped working or in unusable state.
• Occurs when entire functionality is not working or blocked and testing can not be proceeded.

P2/High –

• After the critical category Bug this is the category to fix on prior basis.
• Generally these are the bugs for which affected feature or functionality is usable or working but not in the way as it should.

P3/Medium –

• A defect which might be fix or plan to fix in next release.
• Functionality issue defect which are not as per the expectations.
• These are the bugs which impact the functionality of sub module and workarounds are also there.

P4/Low –

• A defect which can be moved to differed state until the all other priorities defects are fixed.  
• Need to be fix but wait until more serious or sever defects have been fixed.
