通常来说，在采用敏捷方法作为开发流程的项目中，如极限编程，文档很难和迅速变化的项目设计和代码同步。

Typically, in a project that is developed using an agile process, such as Extreme Programming, the documentation cannot keep up with the frequent changes to the project's design and code.

这种方式已经取得了关于软件过程成熟度的比较正式的成果，如能力成熟度模型(CMM)，和敏捷方法，如极限编程和Scrum。

This approach has led to more formal efforts to achieve software process maturity, such as the Capability maturity Model (CMM), and agile methods such as Extreme Programming and Scrum.
