Agile software development principles
The Manifesto for Agile Software Development is based on twelve principles:
- Customer satisfaction by early and continuous delivery of valuable software.
 - Welcome changing requirements, even in late development.
 - Deliver working software frequently (weeks rather than months)
 - Close, daily cooperation between business people and developers
 - Projects are built around motivated individuals, who should be trusted
 - Face-to-face conversation is the best form of communication (co-location)
 - Working software is the primary measure of progress
 - Sustainable development, able to maintain a constant pace
 - Continuous attention to technical excellence and good design
 - Simplicity—the art of maximizing the amount of work not done—is essential
 - Best architectures, requirements, and designs emerge from self-organizing teams
 - Regularly, the team reflects on how to become more effective, and adjusts accordingly
