This transformation is from the abstract to the concrete and leads fairly directly to the final level, which describes the actual implementation of the model into a deliverable product or service.

这一转换是从抽象到具体，并相当直接地通向最终级别，其描述了从模型到一个可交付产品或服务的实际的实施。

youdao

In each iteration, you do some requirements, design, implementation, and testing of your application, thus producing a deliverable that is one step closer to the final solution.

在每次迭代中，你完成一些需求，设计，实现，和对你的应用程序的测试，因此产生了一个距最终方案更进一步的发布。

youdao

Other artifacts aid in creating the code, but the final design deliverable is the code itself, suggesting that design in software cannot be abstracted away from code.

其他工件只能为创建代码提供帮助，但是最终的设计成果还是源代码本身，这意味着软件中的设计不能脱离源代码。
