There are these values in the software development process:

(1) individuals and interactions are better than processes and tools. (2) working software is better than comprehensive documentation. (3) customer cooperation is better than contract negotiation.

(4) responding to changes is better than following a plan.

The software process proposed above is called agile process, the most important of which is extreme programming (Extreme Programming,XP).

XP is a rule for business and software development, and its role is to focus their efforts on common and achievable goals. It is a methodology aimed at software that meets the needs of customers. XP enables developers to respond more effectively to changes in customer needs, even in the later stages of the software life cycle. It emphasizes that software development is a process of cooperation between people, so a successful software development process should make full use of people's advantages, weaken people's shortcomings, and highlight people's role in the process of software development. Extreme programming is a lightweight approach, thinking that documentation and architecture are not as straightforward as direct programming.

Effective practice of extreme programming

(1) customers as members of the development team (2) use user material (3) short delivery cycle (4) acceptance testing (5) pair programming (6) test-driven development (7) collective ownership (8) continuous integration (9) sustainable development speed (9) open workspace

(10) timely adjusted plan (11) simple design (12) refactoring (13) using metaphor

There are four core values in extreme programming that we must pay attention to in development: Communication, Simplicity, Feedback and Courage.

XP uses "communication, simplicity, feedback and courage" to reduce the pressure and burden of development; whether it is terminology naming, monographs, content and way of narration, and process requirements, you can feel a relaxed and active attitude and atmosphere. This is a means to help understand and more easily stimulate human potential. With his own practice, XP has successfully broken the traditional idea that software engineering "must be heavy" in order to succeed.

The spirit of XP can inspire us to learn and deal with rapidly changing and diverse development technologies. The key to successfully learning XP is to treat XP; with a relaxed and happy attitude of "communication, simplicity, feedback and courage" to feel the practical ideas of XP; after serious practice, through the analysis of real feedback, to determine the value of XP to yourself; have the courage to accept it, or improve it.
