XP is a software development methodology that emphasizes simplicity, communication, feedback, and courage. It is often used in Agile development and can be scaled to larger teams and projects using the Scaled Agile Framework (SAFe).
The goal of XP in Scaled Agile is to improve collaboration and deliver working software more quickly by using pair programming, continuous integration, and test-driven development. Agile leaders and teams would use scaled Agile practices such as Program Increment Planning (PI) and Solution Intent to align their work with the organization's objectives.
Combining Scaled Agile Framework (SAFe) and XP is possible. SAFe is an Agile framework, and XP is a practice. Rather than blindly adopting any method, organizations should evaluate and tailor their approach to meet their specific needs.
Professional certification and training are also recommended. The professionals can provide you with more detailed knowledge and real-world experience of using XP in Scaled Agile.
Kent Beck provides an introduction to the Extreme Programming (XP) software development methodology:
Communication: Clear and open communication is essential for a successful XP project.
Simplicity: The code and design should be as simple as possible and easy to understand and change.
Feedback: XP projects rely on constant feedback from customers and the development team.
Courage: XP requires courage to face and overcome challenges and to make necessary changes.
Pair programming: Two programmers work together at one computer, sharing knowledge and expertise.
Test-driven development: Tests are written before the code, and the code is written to pass the tests.
Continuous integration: Code is integrated and tested frequently to catch and fix bugs early.
Refactoring: The code is regularly reviewed and improved to make it simpler and easier to understand.
Planning game: The customer and development team work together to plan and prioritize the project.
