We follow these principles:
- 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 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 behavior accordingly.
