Q&A
3. My expectations from you
• Let’s focus on Software Projects
• Keep away your day to day stuff for a while
• Listen with an open mind
Consider yourself as a child who has a fresh mind
and is learning a new thing
OR may be as someone who is offered a job to work
as a scrum master
• Don’t relate things to your work as you do it today – at
least during the theory session
• Don’t get stuck with the thought that it is all world of
dreams and not possible practically
4. What is Scrum?
• Scrum is an agile process that allows us to focus on delivering the
highest business value in the shortest time.
• It allows us to rapidly and repeatedly inspect actual working software
(every two weeks to one month).
• The business sets the priorities. Teams self-organize to determine the
best way to deliver the highest priority features.
• Every two weeks to a month anyone can see real working software and
decide to release it as is or continue to enhance it for another sprint.
6. Scrum has been used for
Commercial software Video game development
In-house development Satellite-control software
Contract development Websites
Fixed-price projects Handheld software
Financial applications Network switching
applications
7. Characteristics
Self-organizing teams
Product progresses in a series of two-to four-week
“sprints”
Requirements are captured as items in a list of “product
backlog”
No specific engineering practices prescribed
One of the “agile processes”
8. The Agile Manifesto
The Scrum Framework implements the cornerstones
defined by the agile manifesto
Individuals and
over Process and tools
interactions
Comprehensive
Working software over
documentation
Customer
over Contract negotiation
collaboration
Responding to
over Following a plan
change
10. What is a Sprint?
In the Scrum Framework all activities needed for the
implementation of entries from the Scrum Product
Backlog are performed within Sprints (also called
'Iterations'). Sprints are always short: normally about 2-4
weeks.
Each Sprint start with two planning sessions to define the
content of the Sprint: the WHAT-Meeting and the HOW-
Meeting. The combination of these two meeting are also
defined as Sprint Planning Meeting.
In the WHAT-Meeting the Scrum Team commits to the User
Stories from the Scrum Product Backlog and it uses a
HOW-Meeting to break the committed User Stories into
smaller and concrete tasks. Then implementation begins.
11. Sequential vs. overlapping development
Requirements Design Code Test
Rather than doing all of one
thing at a time...
...Scrum teams do a little of
everything all the time
12. No changes during a sprint
Change
Plan sprint durations around how long you can commit to keeping
change out of the sprint
14. Product owner
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
15. The Scrum Master
Primary job is to remove impediments to the ability of
the team to deliver the sprint goal.
Represents management to the project.
Responsible for enacting Scrum values and practices.
Ensure that the team is fully functional and productive.
Enable close cooperation across all roles and functions.
Shield the team from external interferences.
16. The team
Typically 7-9 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
17. The WHAT and HOW Meeting
(time-boxed: 8 hours)
At the beginning of any Sprint (iteration 1-4 weeks), two half:
* BackLog selection (WHAT to do)
+ Some of Product Backlog (user stories) will be chosen to
be (time-boxed: 8 hours)
At the beginning of any Sprint (iteration 1-4 weeks), two half:
* BackLog selection (WHAT to do)
+ Some of Product Backlog (user stories) will be chosen to
be Sprint Backlog.
+ Business value : is set by the Product Owner (client
representative).
-> represents PRIORITY: how Important the story is to the client.
+ Development effort : is set by the Team.
-> represents COMPLEXITY: how Hard to implement the story
according to the average developer’s experience.
User Story: As a [USER] , I want [Feature X] so that [Y
satisfied]
18. Planning Task
* Task estimation (HOW to do)
◦ + each user story is broken down into concrete tasks, and for
each task every group “votes” a number as “the estimated
points” for the task.
◦ + Planning poker cards: for displaying the “voted/estimated”
points. One task point is implicitly considered 1 man hour, for
simplicity. (note: some may use 1 man day for 1 story point).
19. Planning Estimation
* Task estimation (HOW to do)
◦ + If the points from the groups for the task are
unanimous, or similarly (highest number is not higher than
1.5 the lowest number), the “final estimated points” is
determined and marked into the task.
◦ + If the points of the group are not similarly (see above),
the groups of highest number and lowest number will, in
turn, tell the team why they think their number is suitable.
After that all groups will re-estimate that task again. (this step
may be repeated several times until a compromise is reached)
◦ + Total estimated points for a story should not exceed a
predefined certain amount (20-40 man hours), otherwise the
story may either be labeled as “epic” to be broken into smaller
stories so as to not violate that limitation.
20. The Daily Stand-Up
Time: short (usually 5-15 minutes)!
It should start at the same time every working day (practically 15-
45 mins after start working time).
Venue: near the collaboration space,
i.e. near the Scrum taskboard enough to see the characters there.
Agenda: Everybody tells others about his tasks, in 3 points:
+ What has he done since the previous stand-up ? (DONE’s
yesterday)
+ What is he planning to do today ? (DO’s today)
+ Is there any obstacle preventing him/her from doing what
he/she has planned ? (any IMPEDIMENT)
21. The Sprint Review Meeting
Review meeting (time-boxed: 3-4 hours)
◦ internal showcase for whole team
◦ demonstrate what is being done
◦ direct feedback (incomplete features do not count)
Typically takes the form of a demo of new features or underlying
architecture
No slides
Whole team participates
Invite the world
22. The Sprint Retrospective
Retrospective meeting (time-boxed: 2-3 hours)
(All Scrum team members raise their opinions about the Sprint, in
3 topics)
◦ what we did well?
◦ what did not go well?
◦ which improvement should be applied right next Sprint?
23. What is a 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
Prioritized by the product owner
Reprioritized at the start of each sprint
24. What is a Sprint Backlog
Individuals sign up for work of their own choosing
Estimated work remaining is updated daily
Work for the sprint emerges
If work is unclear, define a sprint backlog item with a larger amount
of time and break it down later
Update work remaining as more becomes known
26. The sprint Burndown chart
Burn chart is a graphical representation of work left to do
versus time.
tracking the team’s progress & predicting when tasks
will be completed
how many story points the team can earn –
the velocity. It helps predict delivery times based on
27. Definition of Done (DoD)
In order to be able to decide when an activity from the Sprint
Backlog is completed, the Definition of Done (DoD) is used.
It is a comprehensive checklist of necessary activities that
ensure that only truly done features are delivered, not only in
terms of functionality but in terms of quality as well.
The DoD may vary from one Scrum Team to another, but must
be consistent within one team.
There might be different DoD at various levels:
◦ DoD for a Scrum Product Backlog item (e.g. writing code,
tests and all necessary documentation)
◦ DoD for a sprint (e.g. install demo system for review)
◦ DoD for a release (e.g. writing release notes)
