What are the 12 principles of Agile?

The 12 principles of Agile, formulated in the Agile Manifesto, are aimed at flexible and efficient project management:

1. Highest priority — satisfying the customer through early and continuous delivery of valuable software.
2. Welcome changing requirements, even late in development.
3. Deliver working software frequently, from a couple of weeks to a few months, with a preference for shorter timescales.
4. Business people and developers must work together daily throughout the project.
5. Projects are built around motivated individuals, who should be provided with the environment and support they need.
6. The most effective and efficient method of conveying information is face-to-face conversation.
7. Working software is the primary measure of progress.
8. Sustainable development: sponsors, developers, and users should be able to maintain a constant pace indefinitely.
9. Continuous attention to technical excellence and good design enhances agility.
10. Simplicity—the art of maximizing the amount of work not done—is essential.
11. The best architectures, requirements, and designs emerge from self-organizing teams.
12. Regularly reflect on how to become more effective, then tune and adjust behavior accordingly.

These principles help create flexible, adaptive, and customer-oriented development processes.
