8. Principles
behind Agile
Manifesto
■ 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.
