While there is value in the items on the right, we value the items on the left more.
- Our highest priority is to satisfy the customer through early and continuous delivery of valuable software,
- Welcome changing requirements, even late in development. Agile processes harness change for the customer’s competitive advantage.
- Deliver working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale,
- Business people and developers must work together daily throughout the project.
- Build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done,
- The most efficient and effective method of conveying information to and within a development team is a face-to-face conversation,
- Working software is the primary measure of progress.
- Agile processes promote sustainable development. The sponsors, developers, and users should be able to maintain a constant pace indefinitely,
- Continuous attention to technical excellence and good design enhances agility,
- Simplicity – the art of maximizing the amount of work not done – is essential,
- The best architectures, requirements, and designs emerge from self-organizing teams,
- At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behaviour accordingly.
