🔄 Agile and the 12 Principles

Agile is a flexible, customer-focused approach to software development that promotes rapid value delivery and adaptability. Originating from the Agile Manifesto (2001), its 12 core principles guide teams in dynamic environments.

The 12 Agile Principles:

  1. Customer satisfaction through early and continuous delivery.

  2. Welcome changing requirements, even late in development.

  3. Deliver working software frequently, in short cycles.

  4. Close collaboration between business and developers.

  5. Build around motivated individuals and trust them.

  6. Face-to-face conversation is the best communication.

  7. Working software is the main progress measure.

  8. Maintain a sustainable pace of development.

  9. Focus on technical excellence and good design.

  10. Simplicity is essential – maximize work not done.

  11. Self-organizing teams produce the best results.

  12. Regularly reflect and adjust behavior for effectiveness.

🌪️ VUCA World (Volatility, Uncertainty, Complexity, Ambiguity)

VUCA describes today’s unpredictable project environments:

  • Volatility: Rapid and unexpected changes (e.g., price swings).

  • Uncertainty: Future is unclear (e.g., unclear client needs).

  • Complexity: Many interconnected factors (e.g., global teams).

  • Ambiguity: Lack of clarity in decision-making (e.g., tech choices).

Agile methods (like Scrum) help teams thrive in VUCA by embracing change and continuous improvement.

⚖️ Agile vs. Traditional Methods

Agile Traditional
Adaptive and iterative Rigid and sequential
Frequent customer feedback Feedback mainly at the start
Self-organizing teams Hierarchical team structure
Embraces change Resists late-stage changes

🧠 KISS Principle (Keep It Simple, Stupid)

Focus on simplicity in design and code to avoid unnecessary complexity. Agile values simplicity for faster, safer iterations.

🚀 CI/CD (Continuous Integration / Deployment)

CI/CD ensures rapid, automated integration, testing, and deployment of code. Supports Agile by enabling frequent, reliable delivery of working software.

🎮 Practical Agile Application: Resource Management Game

  • Concept: A console-based simulation where resources flow down hierarchical levels.

  • Phases:

    1. Requirements and planning (levels, resource flow).

    2. Iterative development (classes, logic, testing).

    3. Player decision-making and survival mechanics.

  • Agile Focus: Frequent testing, iteration, and feedback integration.
