Extreme Programming

An Agile software development methodology that emphasizes customer satisfaction, teamwork, and frequent delivery of small, functional software increments.

Practices Employed

• Approvals: XP involves customer approval during frequent releases and continuous customer involvement.
• Automated Testing: XP emphasizes writing tests before coding, ensuring that the software meets its requirements from the start. See:
  • Test Driven Development (TDD)
  • Unit Testing
• Automation: XP emphasizes the use of automated tests to ensure the software works as expected. See:
  • Automated Testing
• Coding: Coding is a core activity in XP, with an emphasis on clear, simple code.
• Configuration Management: Configuration management helps maintain the consistency of the product's performance in XP.
• Debugging: Debugging is an essential part of the development process in XP.
• Design: XP Emphasizes the simplest design that works, avoiding unnecessary complexity. See:
  • Simple Design
  • Metaphor
• Documentation: XP values communication, which can include necessary documentation, but prioritizes working software and direct communication.
• Estimating: XP uses practices like planning games to estimate the time and resources needed for tasks. See:
  • Planning Game
• Integration Testing: XP practices include integrating code into a shared repository frequently, which helps in identifying integration issues early. See:
  • Continuous Integration
• Monitoring: Monitoring progress through daily stand-ups and frequent releases is integral to XP. See:
  • Daily Stand-ups
• Pair Programming: XP encourages two developers working together at one workstation, which improves code quality and facilitates knowledge sharing. See:
  • Collective Code Ownership
• Performance Testing: Ensuring the software performs well under expected workloads is a practice within XP.
• Refactoring: XP encourages continuous refactoring to improve the design of existing code and maintain its quality.
• Release Delivery: XP focuses on frequent, small releases to ensure the software is always in a shippable state.
• Requirements Capture: XP captures requirements through user stories and continuous dialogue with the customer. See:
  • User Stories
• Retrospectives: XP relies on continuous feedback from tests, customers, and developers to improve the software. See:
  • Continuous Feedback
• Review: XP includes regular reviews to assess progress and make necessary adjustments.
• Stakeholder Management: XP involves customers directly in the development process to ensure the software meets their needs. See:
  • Customer Involvement
  • On-Site Customer
• Tool Adoption: XP teams often adopt specific tools to manage the backlog, tests, and collaboration. See:
  • Coding Standards
• Training: XP teams engage in continuous learning and improvement, often through practices like pair programming.
• Version Control: Version control is a best practice in software development, including in XP.

Description

"Extreme Programming (XP) is a software development methodology which is intended to improve software quality and responsiveness to changing customer requirements. As a type of agile software development, it advocates frequent 'releases' in short development cycles, which improves productivity and introduces checkpoints at which new customer requirements can be adopted." - Extreme Programming, Wikipedia

Extreme Programming (XP) is an Agile framework that emphasizes customer satisfaction, teamwork, and frequent delivery of small, functional software increments. Key practices in XP include pair programming, test-driven development, continuous integration, refactoring, and simple design. XP focuses on improving software quality and responding to changing customer requirements through frequent releases and continuous feedback.

In addition to the practices described above, XP promotes a sustainable work pace to avoid burnout, encouraging a maximum of 40-hour work weeks and avoiding overtime as much as possible.
