In this article, we would like to list the main rules of Scrum which are written by Mike Cohn in User Stories Applied For Agile Software Development book.
Rules of Scrum
A sprint planning meeting is held at the start of each sprint.
Each sprint must deliver working and fully tested code that demonstrates something of value to end-users or the customer.
The product owner prioritizes the product backlog and it may be added to or reprioritized at anytime.
The team collectively selects the amount of work brought into the sprint. Once a sprint begins, only the team may add to the sprint backlog.
A short scrum meeting is held every day. Each project participant answers: What did you do yesterday? What will you do today? What obstacles are in your way?
The result of a sprint is demonstrated at a sprint review meeting at the end of the sprint. No slideshows are allowed. No more than two hours may be spent preparing for the sprint review.
