This document provides an overview of Agile Scrum concepts including: - The challenges of traditional software development that Scrum addresses like changing requirements and incomplete understanding at the start. - The Scrum framework focuses on iterative development with 3 roles - Product Owner, Scrum Master, and Development Team. - Scrum uses artifacts like the Product Backlog, Sprint Backlog and Burn Down Chart to track work. - Events in Scrum include Sprint Planning, Daily Scrums, Sprint Review and Retrospective which are timeboxed meetings. - Key techniques in Scrum are story point estimation, adjusting sprint length based on factors like uncertainty, maintaining a transparent backlog, and allowing some changes during

SCRUM THEORY AND CONCEPT
Chapter 1

4. CONFIDENTIAL
Challenges in Software Development
• Requirements change
• Customers never knows exactly what they need
• Requirements are incomplete
• People rarely understand requirements from the beginning
• People make mistakes but it’s hard to fix them on the latter stages of development
• For most middle-to-large systems, it is hard (impossible) to design everything in
advance

The Scrum Team
9
There are three roles in a Scrum project; no less, and no more.
• 1 person
• Full-time or Part-time
• Business oriented
• 1 person
• Full-time or Part-time
• Scrum coach and
facilitator
• 3 to 9 people
• Full-time (recommended)
• Specialist
Other persons can also be involved in and potentially affect the project but they are not considered internal to the
project:
• Company manager
• Customer
• End user representative…
They are called Stakeholders

10. CONFIDENTIAL
So, Who is the Project Manager?
10
• There is no such role in Scrum
• None of the 3 roles of Scrum act as a traditional project manager.
• Some people consider the Scrum Master to be the equivalent to
traditional project manager; but it is not true
• The project management responsibilities are distributed among the
three roles of Scrum and there is no centralized project management
in Scrum

Sprint planning
16
• Development Team asks Product Owner enough questions about high level user stories to
• turn a high-level user story into more detailed tasks in Sprint Backlog.
• estimate the size of the user story.
• Not necessarily completed in this meeting: having a detailed plan for the first few days is enough.

17. CONFIDENTIAL
Daily scrum
17
• What I did yesterday?
• What I plan to do today?
• What impediments are preventing progress?

18. CONFIDENTIAL
Sprint review
18
• Should be informal, no need to spend much time prepare nice documentations.
• Output of Sprint Review is updated Product Backlog

19. CONFIDENTIAL
Sprint retrospective
19
• Two main questions are asked in the sprint retrospective:
• What went well during the sprint?
• What could be improved in the next sprint?

KEY TECHNIQUE

21. CONFIDENTIAL
Key technique
21
• Estimation:
• Function point 1,2,3,5, 8, 13 (know how to handle) -> 13, 20, 40,
100 (undermined, story need to broken down)
• First, find an item that’s small in size, but not the smallest item—that’s
your first 2-point story.
• find another story that’s between 2x and 4x the size of your 2-point
story—that’s your first 5-point story.
• Sprint length
• Business, risk appetite, delivery frequency
• Overall length of release
• Uncertainty (change, technology stack, ..)
• Backlog transparency
• As A, I wanna to do smt at, … (5W).
• Make sure all member + stakeholder could clear abt backlog

22. CONFIDENTIAL
Key technique
22
• Epic vs Story vs Requirement Document = Requirement group vs
Requirement entry point vs Requirement
• Scope of work
• Make clear DoD, make clear task gradationally
• Change requirement during Sprint
• As taught, NO, but in fact in both theory and practice it is YES if
following condition is satisfied:
• Source of change: The change has been confirmed with the customer.
• Timing: The change has been identified at least X (2-3) days before the
end of sprint.
• Purpose: The change aligns well with the value proposition of a story in
the sprint
• Size: The change is small – up to X hours.
• Release
• Delivery frequently, since earlier stage, is a key point to get feedback
and success.
