The principles behind XP are based on the values just described and are intended for: Facilitating decisions in a system development project.
The principles want to be more concrete with respect for values and easier to translate into guidance in a practical situation.
Feedback Extreme Programming sees feedback as very helpful when done quickly and indicates that The time between an action and the feedback is crucial for learning and making changes. not how traditional methods of system development, customer contact is more frequent iterations.

The customer has clear insight into the system that is being developed. He or she can give feedback and steer the development as needed. Unit tests also contribute to the rapid feedback principle.
When writing code, the unit test provides direct feedback as to how the system reacts to the changes one has made.
If, for instance, the changes affect a part of the system that is not in the scope of the programmer who made them, that programmer will not notice the flaw. There is a high probability that this error will appear. The system is in production.
The second is based on simplicity Solving each problem is treated as if it were “very simple”. traditional system The development method tells you to plan ahead and plan for reuse. extreme programming Reject these ideas.
Proponents of extreme programming say that making big changes all at once doesn’t work. Extreme programming implements incremental changes. For example, the system may be small. Issued every 3 weeks.
With many small steps, the customer has more control Development process and development system. III. Accept the change The principle of acceptance of change is acceptance of change, not opposition to it.
For someone For example, in one of the regular meetings, the client If it changes significantly, the programmer must accept it and plan new requirements. Next rehearsal.
Extreme programming project From a practical point of view, the following steps are as follows: myself. User story User stories serve the same purpose as use cases, but they are not.
They are used to Estimate the time for the release planning meeting. It is also used in place of large ones. Requirements document.
User stories are written by customers based on system needs for them They are similar to usage scenarios, except they don’t just describe Their user interface in the form of about three sentences of text written by the customer Customer conditions without technical syntax. User stories also trigger acceptance tests.
one or more automatic logins Tests need to be created to verify that the user’s story is implemented correctly. one of the biggest User story misunderstandings is different from traditional requirements Technical Specifications. The biggest difference is in the level of detail.

User stories are only allowed to make suggestions Enough detail to estimate the relatively low risk of how long the story will last Implementation. When it’s time to execute the story, the developers go to the client and You get a detailed description of the requirements face-to-face.
The developers estimate how long Stories must be performed. Each story receives an “ideal” quote of one, two, or three weeks of Development time “.
This is the ideal development time for story implementation. If the code had no distractions or other tasks and knew exactly what to do. More than 3 weeks means the story needs to be clearer.
