There are many different opinions about if team should have Sprint 0 or not. In my opinion, Sprint 0 is a good for team, because it could avoid team to take pressure immediately if no more Sprint 0.1, 0.2, 0.3...etc. What will I do in Sprint 0? Here is a task list of Sprint 0. * Kick-Off * Agile/Scrum training.

(PO) * Define DoD. (Team) * Prepare developing/testing/integration environment. Wish this helps. regards, Stanley Huang
