We are uncovering better ways of developing
software by doing it and helping others do it.
Through this work we have come to value:
- Individuals and interactions over processes and tools
- Working software over comprehensive documentation
- Customer collaboration over contract negotiation
- Responding to change over following a plan
12 principles …
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.
