通常，所有这些代码都与应用程序逻辑交织在一起，从而使得应用程序维护有些困难。
Usually, all this code is intertwined with application logic, making it cumbersome for application maintenance.
减少代码有很多好处，包括性能(连接所涉及的代码量对于脚本而言非常值得考虑)，但也会减少我们以往的交织依赖关系。
Reducing the code had many benefits, including performance (code size over the wire is where it really counts with script) but also in reducing the tangled dependencies we used to have.
面向过程的代码所具有的包含诸多相互交织的接口的特点对于SCRUM技术是不合适的。
Procedural code, with its many and intertwined interfaces, is inappropriate for the SCRUM methodology.
