敏捷開發12條原則
We follow these principles:
1.我們最重要的目標，是通過持續不斷地及早交付有價值的軟體使客戶滿意。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.
6.不論團隊內外，傳遞資訊效果最好效率也最高的方式是面對面的交談。The most efficient and effective method of conveying information to and within a development team is face-to-face conversation.
7.可工作的軟體是進度的首要度量標準。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.
11.最好的架構、需求和設計出自自組織團隊。The best architectures, requirements, and designs emerge from self-organizing teams.
12.團隊定期地反思如何能提高成效，並依此調整自身的舉止表現。At regular intervals, the team reflects on how to become more effective, then tunes and adjusts its behavior accordingly.
