Four major condition of Defect :-

• High Severity & High Priority : This condition happens, When defect effects whole application as well as customer. Like you enter login credentials but application don't shows homepage.

• High Severity & Low Priority : This condition happens, when defect effect functionality more then business. Like some functionality of application doesn't work on old version of browser, because only some people used old version of browser so it won't effect on business.

• Low Severity & High Priority : This condition happens, when defect effect only some functionality but effect business so much. Like the logo of the application doesn't appear. So this condition don't effect any functional area but it effect business because it presents the business value. Without app. logo many user of the application wouldn't trust the application.

• Low Severity & Low Priority : This condition happens, when defect only do minor effect on application as well as business. Like Some module of application has UI defect and this module not have so much user visiting. So this effect will not take so much attention.
