The document provides an overview of the Scrum methodology, a widely-used agile approach to product development that emphasizes a holistic team-based process over linear task execution. It details Scrum roles, rituals, and artifacts, such as the product backlog, sprints, and daily stand-up meetings, emphasizing collaboration and flexibility. Additionally, it outlines the responsibilities of key roles within the Scrum framework, including the Product Owner and Scrum Master.

2. Rugby instead of Relay race
“The… ‘relay race’ approach to product development…
may conflict with the goals of maximum speed and
flexibility. Instead a holistic or ‘rugby’ approach—where
a team tries to go the distance as a unit, passing the ball
back and forth—may better serve today’s competitive
requirements.”
Hirotaka Takeuchi and Ikujiro Nonaka,
“The New New Product Development Game”, Harvard
Business Review, January 1986.

8. Characteristics
• Self-organizing teams
• Product progresses in a series of 2-4 weeks “sprints”
• Requirements are captured as items in a list of “product
backlog”
• No specific engineering practices prescribed nor forbidden
• One of the “agile processes”

9. Agile Scrum rules

10. Putting it all together

11. Sprints
• Scrum projects make progress in a series of “sprints”
• Analogous to Extreme Programming iterations
• Typical duration is 2–4 weeks
• A constant duration leads to a better rhythm
• Shorter sprint leads to faster impediment solutions
• Product is designed, coded, and tested during the
sprint

12. No changes during a sprint
• Plan sprint durations as long as you can commit
to keep change out of the sprint

15. Product owner role
• Define the features of the product
• Decide on release date and content
• Be responsible for the profitability of the product (ROI)
• Prioritize features according to market value
• Adjust features and priority every iteration, as needed
• Accept or reject work results

16. ScrumMaster role
• Not a project manager but a facilitator
• Responsible for Scrum values and practices
• Removes impediments
• Ensure that the team is fully functional and productive
• Enable close cooperation across all roles and functions
• Shield the team from external interferences

17. Team
• Typically 5-9 people
• Cross-functional:
• Programmers, testers, user experience designers, etc.
• Members should be full-time
• May be exceptions (e.g., database administrator)
• Teams are self-organizing
• Ideally, no titles but rarely a possibility
• Membership should change only between sprints

19. Sprint planning meeting
Sprint planning
• Analyze and evaluate product backlog
• Create sprint backlog from product
backlog items (user stories / features)
• Estimate sprint backlog stories in
relatives Story Points
• Decompose stories in tasks
• Evaluate tasks in days or hours.

20. Sprint planning
Team selects items they can commit to finish from the
prioritized product backlog
• Sprint backlog is created
• Stories are identified and decomposed in tasks
• Each task is estimated such as it does last 1 or 2 days
• Collaboratively, not done only by the ScrumMaster
• Business value is considered (eg: Web travel agency)
As a “tourist”(1), I
want to “see photos
of the hotel”(2) so
that “I am sure it is
near the sea”(3).

Code the database access (1 d)
Code the user interface (2 d)
Write test (1 d)
Code the foo class (0.5 d)
Update performance tests (2 d)
(1): User role, (2): what to do, (3): business value

21. The daily scrum
• Characteristics
• Daily
• 15-minutes
• Stand-up
• Everyone may come
• BUT Only team members including ScrumMaster can talk
• Goal
• Keep the team synchronized and focused
• Update the work done and burndown chart
• Create a team spirit

22. Everyone answers 3 questions
• These are not status for the ScrumMaster
• They are commitments in front of peers
What did you do yesterday?What did you do yesterday?
1
What will you do today?What will you do today?
2
Is anything in your way?Is anything in your way?

23. Sprint Demo/Review
• Team presents what it accomplished during the
sprint
• Typically takes the form of a demo of new features
• Informal
• 2-hours prep time rule
• No slides
• Whole team participates
• Everyone may come and discuss

24. Sprint retrospective
• Take a look at what is and is not working
• Typically less than 1 hour
• Done after each sprint
• Whole team participates
• ScrumMaster
• Team
Start doingStart doing
Stop doingStop doing
Continue doingContinue doing

26. Product backlog
• The requirements
• A list of all desired work on the
project
• Ideally expressed such that each
item has value to the users or
customers of the product (user
stories)
• Prioritized by the product owner
• Reprioritized at the start of each
sprint
This is the product
backlog

28. Managing the sprint backlog
• Individuals sign up for work of their own
• Work is never assigned by someone to someone
• Estimated work remaining is updated daily
• If work is unclear, define a sprint backlog item with a larger
amount of time and break it down later
• Update work remaining if you get more information
– Either thanks to your work
– By discussing with the Product Owner
