Extreme Programming (XP) is actually a deliberate and
disciplined approach to software development. About six years old, it
has already been proven at many companies of all different sizes and
industries worldwide. XP is successful because it stresses customer
satisfaction. The methodology is designed to deliver the software your
customer needs when it is needed. XP empowers software developers to
confidently respond to changing customer requirements, even late in the
life cycle. This methodology also emphasizes teamwork. Managers,
customers, and developers are all part of a team dedicated to delivering
quality software. XP implements a simple, yet effective way to enable
groupware style development.
XP improves a software project in
four essential ways; communication, simplicity feedback, and courage.
XP programmers communicate with their customers and fellow programmers.
They keep their design simple and clean. They get feedback by testing
their software starting on day one. They deliver the system to the
customers as early as possible and implement changes as suggested. With
this foundation XP programmers are able to courageously respond to
changing requirements and technology. XP is different. It is a lot like a
jig saw puzzle. There are many small pieces. Individually the pieces
make no sense, but when combined together a complete picture can be
seen. This is a significant departure from traditional software
development methods and ushers in a change in the way we program.
