From this roadmap, the backlog stories are created. Product owner with the team's help ensures that product backlog is prioritized. Product owner presents the product to customers for feedback while the project is in the development phase. This is different than waterfall model where the customer needs to commit to requirements. 

Team consists of everyone who is responsible for making the project successful. The team signs up for stories in sprint. Each person takes a story and first put estimates for writing story tests, coding and acceptance testing.

The product backlog consists of list of stories which need to be done before the product can be released to the customer. Product owner helps in prioritizing feature list. The best way to create backlog is to define user stories. User stories are description of feature functionality from the perspective of customer who is going to use the system. First task for any project is Sprint zero planning, which consists of spikes for research items.

In sprint zero team create project backlog.  Other prominent artifact is the spring burn down chart and release burn down chart. Burndown is a management tool to find out the remaining work for a sprint or a release. Burndown helps management understand how the project is performing and whether the promised completion date for the project can be met.

Daily scrums help team members to synchronize work and help in resolving any problems which might occur during development and testing. The primary artifact of the scrum is shippable code at the end of sprint. This means the code is written, tested and accepted within the same iteration.

One noteworthy facet of Scrum is the fact that product owner or customer can change the requirements in the middle of implementation. In the waterfall model we wish that the customer knows what he wants. The developers know how to build it. Nothing will change along the way. The reality is opposite of this wishful thinking. We have to live with the customer discovering what he wants. The developers discover how to build software. Many things can change along the way. Agile Scrum development helps in making this possible.
