What happens prior to the Sprints (Pre-Sprint):
- The Vision Statement provides a concise description of the goals of the project which help the team stay focused on what is important from the organization point of view.
- The Product Roadmap is an initial visual timeline of major product features to be delivered and is normally created by the Product Owner.
- Stories are user requirements which will be turned into deliverable features, normally written by the Product Owner based on requirements from the customer.
- All these stories make up the Product Backlog and the first Sprint can start as soon as there is enough stories defined, without the need for the Backlog to have 100% of the details.
