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