The principles of Extreme Programming (XP) focus on improving software quality and responsiveness to changing customer requirements. The key principles include:
Rapid feedback: Getting feedback quickly from customers or stakeholders to ensure that the development process is on track.
Assume simplicity: Focusing on simplicity in the design and code to avoid overengineering and to ensure the software is easy to understand and modify.
Incremental change: Delivering software in small, manageable increments that can be easily adjusted based on feedback.
Embrace change: Being flexible and adaptable, especially in response to new requirements or changes in technology or business needs.
Quality work: Ensuring high-quality software by emphasizing practices such as automated testing, continuous integration, and refactoring.
