Feature (Difference between me and others)
● People oriented management
○ I believe a great software is made by great team.
○ I mean it is “self-organized” or “self-management” team.
● Martin Fowler oriented “Evolutionary Design over Planned Design” technical position.
○ “Evolutionary Design” is the one of keys for Agile project.
○ Fundamental assumption of the design is stand on “OOP, Testing, CI, Refactoring, Business align
mind, Communication”.

6. Waterfall model is also called as a heavy-weight approach.
Waterfall model
Best way, if the requirements are
never changed, because everything
is optimized and planed for it.

7. Cowboy coding
Cowboy coding is software development where programmers
have autonomy over the development process. This
includes control of the project's schedule, languages,
algorithms, tools, frameworks and coding style.
They create low quality software.
One another problem is it might looks Agile if you are
a beginner.

8. Agile
Agile software development is an
approach to software development under
which requirements and solutions evolve
through the collaborative effort of self-
organizing and cross-functional teams
and their customer(s)/end user(s). It
advocates adaptive planning,
evolutionary development, empirical
knowledge, and continual
improvement, and it encourages rapid
and flexible response to change.

12. Google Trends : Japan (https://g.co/trends/fQSC7)
Waterfall is a bit more major.
Additionally sometimes, They misunderstand about Agile.

17. When I was in Waterfall (2010~2015, 2017)
(structure was like this)
Less diversity and pose for genderless. They are good at Excel.
I’m system engineer.
But, I don’t know
engineering so much.

20. But why they choose Agile?

21. Size vs Speed
future
1980 1990 2000 2010 2020
The company size was important for business,
because of the “Economies of scale”.
So, Waterfall was not bad.
Now, The speed is important for business,
because everything is complex and customer
demand is variety.
So, Waterfall is not enough for demand of
evolutionally development.

To everyone
- Think you’re living in the age of Global World.
- “Do given task worker” will be in cost competition with
all over the world. Low cost worker will get job.
- “Solution Worker” is not enough. Customer want to
pay money for them to resolve their problem.
- “Old Solution” will be not able to resolve problem. So,
it’s better to shift ASAP.
