This article is the continue version of the last article (Agile Software development model I)

The technique for development using Agile is as follow.
-Agile model driven development (AMDD)
-Code Refactor : is the method to redesign code that is to modify the code immediately and then
the design is also change.
-Pair Programming : Combine the two developers to work together for the same project.
These two developers work at the same location and
also use the same computer.Share the computer in the way that one
person implement the code and another person has a responsibility for
checking the correction of implemented code.
-Test Driven Development(TDD) : is the technique for writing the test-case and write the test
case before implement the code.

The format(pattern) of Agile.

Agile methodology has many patterns that can be used for developing the system such as Scrum, FDD,
XP (extreme programming), DSDM, RUP, etc…But the popular pattern in my opinion is XP (extreme programming) because XP is the pattern that emphasize on the satisfaction of the customer and XP can change the system easily when the customer change the requirement.

Addition aspect for Agile.
– When we have the old project that can be used for additional development.It mean that
we have the asset that can be used as the base system for develop the new project,
so if the new project arrive then we can send the old project to the customer before sending
the new one.
– In the first step of developing new project,we can also deliver the things such as the screen,
the prototype,infrastructure to our customer without the software (because we have not written
the software yet)
– We also can think about Agile as the modifier of the former software development process such as
– Use Agile for rearrange the importance of the project development activity ,
which activity should be done and which should not be done.
– Use Agile to control the former project and look at some part of former project.The part that
is important for use with the development of new project should be done ,
the unimportant part will be ignored.

Agile

Agile is the new idea for software development
that try to scrape through the old methodology to shorten
the development process.
It is the principle of new software development methodology
that emphasize on the following topic.

– Rapid and flexible response to change
– speed up the development process
- don’t stop, do the development continuously despite
of the things that will affect the development process
- when there is a change, we can support this
alteration rapidly and flexible

The objective of Agile
1.Emphasize on the aptitude of each developer.Try
to commune with each other more than impress on the
tools and methodology.Such as the programmer have a chance
to talk with the customer and can do the project in agreement
with the customer’s requirement.
2.Do the project by concentrate on the result or final
software.The old methodology is concentrate on the document
but Agile is not,the purpose of Agile is that we have a
ready software to send to the customer on the definited time.
3.The main point of Agile is communication.Agile is not
prefer the contact but Agile is stress on the communication
between the customer and developer.
4.Accept the changefulness.The old methodology is must do
follow the plans (gantt chart) but Agile is not necessary to follow the plans.
But Agile must able to respond to the change.

The model of Agile is as follow.

– choose only some methodologies for developing project.
– the chosen methodolgy must be able to use the
priciple of Agile to manage the documents and the existing
system.
– In Agile,It must consist of
– value (result)
– principle
– practices

The three things above are the part of Agile model that
can be use for develop the project efficiently and have
less overhead.

That’s all for this article but the story of Agile is not finish.
In my next articles I will write about technique of development using Agile and other
addition aspect for using Agile.
