system engineering process

Reverse engineering is a process of analysing an existing system to identify its components and their interrelationships and to create representations of the system at a high level of abstraction.

逆向工程是对一个已存在系统的分析处理，以鉴别它的组成部分及它们的内在联系，从而以高层抽象性来构建一个系统的框架。

Forward engineering is a traditional process of moving high-level abstracts and logical, implementation-independent designs to the physical implementation of a system.

正向工程是对一个系统物理结构实现的高层抽象性、逻辑性及独立性设计的传统处理过程。

Traditional requirements engineering, the first step in the software development process, determines the functional and nonfunctional needs or conditions that must be met for a new product or system.

作为软件开发流程中的第一步，传统需求工程确定新产品或系统所必须满足的功能性和非功能性需求或条件。
