Résumé
consistently deliver value to a business and remain under control.
Extreme Programming (XP) was conceived and developed to
address the specific needs of
software development conducted by small teams in the face
of vague and changing
requirements. This new lightweight methodology challenges
many conventional tenets,
including the long-held assumption that the cost of
changing a piece of software necessarily
rises dramatically over the course of time. XP recognizes
that projects have to work to
achieve this reduction in cost and exploit the savings once
they have been earned.
Fundamentals of XP include:
- Distinguishing between the decisions to be made by
business interests and those to be
made by project stakeholders.
- Writing unit tests before programming and keeping all
of the tests running at all times.
- Integrating and testing the whole system--several times
a day.
- Producing all software in pairs, two programmers at one
screen.
- Starting projects with a simple design that constantly
evolves to add needed flexibility
and remove unneeded complexity.
- Putting a minimal system into production quickly and
growing it in whatever directions
prove most valuable.
Why is XP so controversial' Some sacred cows don't make the
cut in XP:
- Don't force team members to specialize and become
analysts, architects,
programmers, testers, and integrators--every XP programmer participates in all of
these critical activities every day.
- Don't conduct complete up-front analysis and design--an
XP project starts with a
quick analysis of the entire system, and XP programmers continue to make analysis
and design decisions throughout development.
- Develop infrastructure and frameworks as you develop
your application, not
up-front--delivering business value is the heartbeat that drives XP projects.
- Don't write and maintain implementation
documentation--communication in XP
projects occurs face-to-face, or through efficient tests and carefully written code.
You may love XP, or you may hate it, but Extreme
Programming Explained will force
you to take a fresh look at how you develop software.

L'auteur - Kent Beck
Kent Beck is the founder and director of the Three
Rivers Institute (TRI). TRI provides a harmonious
environment for individuals from many disciplines to gather
and investigate the principles underlying emergent software
development and techniques for leveraging these principles.
Mr. Beck has pioneered patterns for software development,
the xUnit family of testing frameworks, the HotDraw drawing
editor framework, CRC cards, refactoring, and most recently
Extreme Programming. He is the author or co-author of
Extreme Programming Explained (Addison-Wesley, 2000),
Planning Extreme Programming (Addison-Wesley, 2000), and
The Smalltalk Best Practice Patterns (Prentice Hall, 1996).
He lives on 20 acres in rural southern Oregon with his
wife, five children, four dogs, two sheep, and a variable
number of domestic fowl. He received his undergraduate
degree from the University of Oregon.
