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.
