Severity
refers to the level of impact, the defect has created on the users. Say
If a particular defect has occured in an application and if more than
80% of the users are affected by the defect, the defect type is
"Critical
Similarly if only 50% of the users are affected, in such cases the severity of the incident can be treated as "Seroius".
However priority refers to the "Urgency" with which the incident has to be fixed.
In most of the cases a critical incident can be of high priority, however the vice versa need not be true.
For example a user might request the support team member to
change the font size and font color of the text in a web page and in
this case for the user, it might be of high priority, however it is not
a critical or serious incident.
