Agile Manifesto

Twelve principles underlie the Agile Manifesto, which includes:

Customer satisfaction by rapid delivery of useful software

Welcome changing requirements, even late in development

Working software is delivered frequently (weeks rather than months)

Working software is the principal measure of progress

Sustainable development, able to maintain a constant pace

Close, daily co-operation between business people and developers

Face-to-face conversation is the best form of communication (co-location)

Projects are built around motivated individuals, who should be trusted

Continuous attention to technical excellence and good design

Simplicity

Self-organizing teams

Regular adaptation to changing circumstances
