System boundary
The boundary between a System and its surrounding Context.
Notes:
- The system boundary delimits the system as it shall be after its implementation and deployment.
- At the system boundary, the external interfaces between the System and its Context have to be defined.
- The system boundary frequently coincides with the Scope of a System (which denotes the range of things that can be shaped and designed). However, this is not always the case: there may be components within the system boundary that have to be re-used as they are (i.e., cannot be shaped nor designed), while in the system context there may be things that can be re-designed when the system is developed (which means that they are in scope).
