- Welcome changing requirements, even late in development. Agile processes harness change for competitive advantage.
- Deliver working software frequently.
- Business people and developers must work together daily throughout the project.

- The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
- Working software is the primary measure of progress.
- Agile processes promote sustainable development. Sponsors, developers, and users should be able to maintain a constant pace indefinitely.
- Continuous attention to technical excellence and good design.
- Simplicity - maximising work not done is essential.
- Best architectures, requirements, and designs emerge from self-organising teams.
- At regular intervals, the team reflects on how to become more effective, then tunes its behaviour.
