- 13. Sprint Planning Meeting 1. Product Owner, Team, and other Stakeholders talk through Product Backlog Items and prioritization. 2. Team determines how much time it has available to commit during the Sprint 3 . Team selects as much of the Product Backlog as it can commit to deliver by the end of the Sprint, and turns it into a plan - Validates commitment by breaking down into tasks with time estimates - Team decides who will do what, when; thinks through sequencing, dependencies, possible task trades, and so forth.

- 15. Review/Sprint Demo Team presents the working demo. What have we achieved? Should show finished functionality. What is missing. Maximum of 2 hours for presentation.
- 16. Retrospective Facilitated by Scrum Master To increase productivity and Team reflects on sprint experience and comes up with suggestions. What went well? What did not go so well? How can we improve?
- 17. Burndown chart A graphical representation of work left to do vs. time Work remaining is the Y axis and time is the X axis. Useful to predict when all of the work would complete Release burndown chart Sprint burndown chart
- 18. Why we might fail using scrum? Hard! Scrum does not fix everything Scrum makes problems visible - early Ready for a change? It makes Products to be delivered faster Customized/partial Scrum
- 19. Summary Everything is time-boxed. Inspect & Adapt. You can-not plan everything. Fail early. Shippable product at the end of every iteration/sprint. Iterative incremental development. Cross-functional teams. Self-organizing teams. Team owns the sprint backlog.
