Individuals and Interactions
Over Processes and Tools
The right set of people in a team and their interactions are the keys to success.
The best techniques available are of no value in the wrong hands.
Over Comprehensive Documentation
Don't spend hours making documentation before you write a single line of code.
Documentation is important, but prioritize the delivery of working software to your customers.
Over Contract Negotiation
Customers and the development team are not adversaries.
Collaborate to chart the best way forward together. Establish a feedback loop for your customers to ensure that your product works for them.
Responding to Change
Over Following a Plan
A fixed environment and static road maps do not exist.
Needs and demands will vary, and goals continually change. Adapt and pivot if necessary.
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.
