Example for Priority and Severity

Example for High Priority and High Severity :-

 Suppose there is ATM Machine hope everyone is aware of ATM ma machine which is used for banking transactions. If ATM machine has bug like when user withdraw money from same bank ATM for which he is holding bank account, He is getting charged by 20 rs per transaction. Which is invalid as bank policy says withdrawing money from owns bank ATM no charge will be applied.

So this bug is high priority  because Bank is charging 20 rs per transaction for own ATM which is opposite to business logic. 

and bug is high severity this bug need to resolved immediately because thousands of user withdraw money per hour so it cost high. 

Example for High Priority and Low Severity Bug

Suppose there is ATM machine. Every one use ATM machine for daily transactions.
When you visit ATM machine sometime you may see advertisements from bank on festival season. Suppose on 2nd Oct on occasions of Gandhi jayanti (Last date to do saving is 3rd oct) bank is giving 0.5% extra (basic 5 % + additional 0.5%= 5.5%) additional interest for senior citizens on savings. This advertisement need to flash on or before 3rd oct. Suppose you visited ATM on 4th Oct morning and still you are seeing this add and date displaying in advertisement is 3rd oct last date to do savings.

Here priority is high as advertisement is flashing on multiple ATMs after end of date to do savings. and Impact is not much as date displaying in  advertisement 3rd oct
 means scheme is already over so severity is low . So need to stop this advertisement on priority.

so this is one of example of high priority and low severity
