How is a software created?
Someone wants a software
to meet his needs
investigates and
assigns some people to create one with required
features, that’s called
REQUIREMENTS
And, some of these people draw
something, that’s called
DESIGN
Then others type the statements, follow
the design , that’s called
CODING
After that, other execute the software to make sure
it meets the requirements, that’s called
TESTING
Hopefully, a SOFTWARE will be released with full related documents,
CONTRACT will be paid,CUSTOMER will be over-‐satisfied
Wonderful ending…
But, wait. The fact is…

HOW DOES SCRUM TEAMCREATE A SOFTWARE ??
Someone wants a software
to meet his needs, investigates and assigns some people to
create one with required features, that’s called
REQUIREMENTS
Software creation work is assigned to
Development teamThis team work together and do
PlanningWhat will be done in next
month/weekto have (some) completed feature(s)
to release at end of next month/week
Result of planning meeting
is a
Plan
that includes goals
followed by
work that needs to completed
in this month/week
Work is disseminated to each team member.
Members will work with
close collaboration
The team has daily meeting L
15 minutes/day
to update, check the working
progress, and fix rising issues.
Just-‐in-‐time update plan if
necessary
Iterate working
till end of
time box
Releasable
software
will
be
created
RELEASABLE
software
What will
we have?
Not done yet, development team should have a reflection meeting
HOW did team WORK? Could team work BETTER?Try to find out some points that should be IMPROVED in next month/week
And, repeat that…
Scrum Framework
Differences?
Scrum concentrates on:Collaboration over documentCustomer problem solving over contract signing
Scrum quickly respond to changes!
Customers can receive software right after one month, or one week

BEHIND THE SCENES ...
Agile ManifestoWe are uncovering better ways of developing software by doing it and helping others to do it. Through this work we have come to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
That is, while there is value in the items on the right, we value the items on the left more.
