Features of xp

XP is different. Kind of like quickstep. XP contains many small cards, which seem meaningless independently, but when combined together, a complete and beautiful picture can be seen, which is a new and important development for traditional software development. It has changed the traditional way of thinking for users to develop programs. The following users will introduce the changes it has brought us.

One of the most influential methods in lightweight development. Lightweight development method is relative to the traditional heavyweight development method. Simply understood, the weight of "quantity" refers to the "document quantity" used for software process management and control except program quantity. XP and other lightweight development methods realize that in many cases, a large number of documents established according to traditional concepts, on the one hand, need to consume a lot of development resources, but at the same time, lose the role of helping to "predict, manage, make decisions and control". Therefore, we must re-examine the development link, get rid of the bloated and cumbersome, and go into battle lightly.

Core idea:

In the long run, finding mistakes as early as possible and reducing complexity can save costs. Extreme programming emphasizes that we subdivide the task/system into a subtask/module that can be solved in a short time, and emphasizes testing, code quality and early detection of problems. Usually, through a short iteration cycle, progress can be made in stages, and a version can be formed in time for users' reference, so as to cope with possible changes in users' needs in time.

XP method: plan the game; Pair programming, testing, fire resistance, simple design, collective code ownership and continuous integration. On-the-spot customers release the 40-hour weekly code standard system as a metaphor for the core value;

Extreme programming has five core values that we must pay attention to in development: communication, simplicity, feedback, respect and courage.

empirical value

XP uses "communication, simplicity, feedback, respect and courage" to reduce the pressure and burden of development; We can feel a relaxed, happy and positive attitude and atmosphere, whether it is the naming of terms, the content and method of monograph narration, or the process requirements. This is a means to help people understand and stimulate their potential more easily. XP successfully broke the traditional concept that software engineering must be "heavy" in order to succeed with its own practice.

XP spirit can inspire us how to learn and deal with fast-changing and diverse development technologies. The key to learning XP successfully is to treat XP with an attitude of "communication, simplicity, feedback, respect and courage". Feel the practical ideas of XP with ease and pleasure; After careful practice, I will determine the value of XP to myself through the analysis of real feedback; Have the courage to accept it or improve it.
