1. Extreme Programming (XP) Extreme Programming, or XP, is an agile software development methodology that emphasizes collaboration, communication, and continuous feedback. It aims to improve software quality and responsiveness to changing requirements. HB by Hardik Bhandari

2. Core Practices of XP 1 Pair Programming Two developers work together on the same code, which fosters knowledge sharing and reduces bugs. 2 Test-Driven Development Writing tests before code ensures functionality and helps catch errors early on. 3 Continuous Integration Regularly integrating code changes reduces the risk of conflicts and ensures stability. 4 Refactoring Improving the design of existing code without changing its functionality makes it cleaner and more maintainable.

3. Pair Programming Benefits Reduced bugs, improved code quality, and enhanced knowledge sharing. Process One developer, the "driver," writes code while the other, the "navigator," guides and reviews the code. They switch roles regularly. Key Points Requires trust and communication, can initially feel awkward, but quickly becomes a valuable collaboration tool.

4. Test-Driven Development (TDD) 1 Write a Test Create a test that defines the desired functionality and behavior of the code. 2 Run the Test Execute the test, which will fail initially, as the code hasn't been written yet. 3 Write the Code Write the code to satisfy the test, focusing on the minimal amount of code needed to pass the test. 4 Run the Test (Again) Re-run the test. It should now pass. 5 Refactor Improve the design and structure of the code without changing its functionality.

5. Continuous Integration (CI) Code Changes Developers commit their code changes to a shared repository. Build and Test The code is automatically built and tested. Deployment If the tests pass, the code is automatically deployed to a production environment.

6. Refactoring Benefits Improved code readability, reduced complexity, and enhanced maintainability. Process Involves making small changes to the code while ensuring that all tests continue to pass. Key Points Should be done continuously and not just at the end of a development cycle.

7. Customer Collaboration Frequent Meetings Regular meetings with the customer to gather feedback and ensure alignment. User Stories Capturing user requirements in short, concise stories to ensure clear understanding. On-Site Customer Having a customer representative present during development to provide immediate feedback.

8. Simplicity Focus on the Essentials Only implement features that are absolutely necessary. Prioritize Concentrate on the highest-priority features first. Avoid Over-Engineering Keep the design simple and avoid unnecessary complexity. Time-Boxing Set strict time limits for tasks to avoid getting bogged down.
