There is no software without systems engineering. Software is always part of a bigger system. Even a simple application interacting with a human user consists of software building blocks, a service delivery, various hardware systems, user experience, energy management, connectivity and many more. Systems engineering or "systems thinking," as it is often called, ensures that products deliver more value than the capabilities of their individual parts. Such value beyond the individual components is what we call a system, or even a system of systems. A system is a set of interacting elements that together achieve a purpose.

敏捷系统工程


没有系统工程就没有软件。软件始终是更大系统的一部分。即使是与人类用户交互的简单应用程序也包含软件构建块、服务交付、各种硬件系统、用户体验、能源管理、连接性等等。系统工程或通常被称为“系统思维”，可确保产品提供比其各个部件的功能更多的价值。这种超越单个组件的价值就是我们所说的系统，甚至是系统的系统。系统是一组相互作用的元素，它们共同实现一个目的。
