Software Defect Severity Classification

by admin

Defect Severity can be classified into four categories as i stated below:
1.Severity 1 which is also called as Showstopper. Software tester should report the defect as Severity 1/Showstopper whenever the system/application under test is out of service. In other words, there is no work around or not usable to use the system/application unless the developer fix the defect for further usable.
Example: User unable to launch ‘Funds Transfer’ page in a Banking application. When user clicks on ‘Funds Transfer’ button from Banking application home page the ‘Technical Problems’ or ‘Page Not Found’ displayed to the user.
2.Severity 2 which is also called as Critical. Software tester should report the defect as Severity 2/Critical whenever major function of the system/application under test not working. In other words, the intent of the application functionality is not usable and no workaround exists to use the application functionality unless the developer fix the defect for further usable.
Example: User able to launch ‘Funds Transfer’ page in a Banking application successfully but the ‘Complete Transfer’ button not clickable to initiate funds transfer.
3.Severity 3 which is also called as Major. Software tester should report the defect as Severity 3/Major whenever major function of the system/application under test not working but there is a temporary workaround exists to use the system.
Example: User able to launch ‘Funds Transfer’ page in a Banking application successfully and ‘Complete Transfer’ button is clickable to initiate funds transfer. But the application allows to transfer the money up to $1000 and not more than $1000. As a workaround user has to initiate funds transfer 2 times in order to transfer $2000 with each transfer of $1000.
4.Severity 4 which is also called as Minor. Software tester should report the defect as Severity 4/Minor whenever components of the application are not functioning to specification but the situation is manageable i.e fix can be instituted in a future release.
