The Agile Manifesto
We open up better ways to develop software by doing it ourselves and helping others do it. Through this activity we have learned to appreciate these values:
- Individuals and interactions more than processes and tools
- Functioning software more than comprehensive documentation
- Cooperation with the customer more than contract negotiation
- Responding to change more than following a plan
This means that although we find the values on the right side important, we estimate the values on the left side to be higher.
Principles behind the Agile Manifesto
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.
