What does the term "system integration" refer to in systems engineering?

The concept of "system integration" in systems engineering specifically denotes the process of combining various subsystems into a coherent and functioning whole. This definition highlights the importance of ensuring that all parts of a system work together seamlessly to achieve a common purpose. In systems engineering, integration involves not only bringing together different components but also addressing potential interface issues, compatibility, and collaboration between diverse technologies, processes, and disciplines.

In this context, the focus is on creating a unified system that fulfills its intended functions effectively, which requires careful planning, testing, and adjustment of the elements involved. The integration process is crucial because it can significantly affect the overall performance and reliability of the system. Proper system integration ensures that all parts communicate effectively, behave as expected, and contribute positively to the desired outcomes of the entire system.
