Overview of the agile software development. This contents was originally created for my team's internal workshop. It includes basic concept of the agile software development, and introduction of some practices and tools for it.

1. Agile Software Development
Team workshop on July 11th

2. Today’s theme
In this workshop, I will introduce the basic knowledge of the agile software
development and would like to discuss with you about the applicability of the
agile software development to our team.

3. Agenda
 What does “agile” mean?
 Manifesto for Agile Software Development
 Agile development practices
 Agile development tools
 Suitable situation to adopt agile model

4. What does “agile” mean?
Agile software development is one of the software development methods. The
main feature is to break tasks into small increments (iterations, typically 1-4
weeks) and release new functions in each iteration, which minimize risks and
adopt to changes quickly.

There are many frameworks, method which are included in or compatible with agile development;
 Extreme programming
 Scrum
 Feature driven development (FDD)

5. Manifesto for Agile Software Development
In 2001, 17 Gurus of Agile development discussed and issued the manifesto
below. Agile development prioritizes practical benefit from software than strict
rules and documentation.
We are uncovering better ways of developing
software by doing it and helping others 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.

6. Agile development practices
Based on practical experiments, agile developments have many practices which
can be adopted individually.

Two members work together to develop or
test programs at one PC. This practice can
improve quality and decrease dependencies
on individual skills.
Automation of (especially regression) testing
derives less time-consuming works and
consistent quality of systems. The benefit of
automation will be amplified by adopting
refactoring and TDD.
Restructure existing program logic without
changing its behavior. This improves
maintainability of applications, that is, low
impact analysis and CR efforts.
Build a test script first, being consistent with
requirements. After that, to pass that
test, build a actual program logic. This style
let developers imagine how the functionality
is used by users.
Merge all development works (application
logics, table structure etc.) with a shared
mainline several times a day. Team
can avoid or minimize integration problem.
A technique of estimation. Members shows
numbered cards with relative size of
estimated effort, not with absolute size. With
the result, discussion will be held to make a
consensus.

7. Agile development tools
There are many tools which encourage productivity of system developments, not
only in the context of agile, but also DevOps.

8. Suitable situation to adopt agile model
It is suitable for a small and proficient team combating many changes to adopt
Agile model. How do you think which model to be taken for our team?
 Low criticality system
 More senior developers than juniors
 Requirements change often
 Small number of developers (around 10)
 Culture that responds to change
 High criticality system
 More junior developers than seniors
 Requirements do not change often
 Large number of developers
 Culture that demands order
Agile model
will suit
Waterfall model
will suit

9. Message
Modernize, Industrialize, Digitalize!
 Reduce manual operations
 Reduce EXCEL management & documentation
 Enjoy new technologies & frameworks
