Dear All,
Recently i have an issue in implementing scrum in our company. the case happened as following: in the middle of sprint which it's length is one month, one of our customer raised a blocker bug in our system. and the customer clarify that if his work stop more than 8 hours he will execute a penalty on us. so in our case, we interrupted the Sprint, fixed the bug, tested it and released an increment in middle of Sprint. what is correct practice in Scrum to deal with cases like this.
