System boundary

System boundary - glossary term (IREB Requirements Engineering)

The boundary between a System and its surrounding Context.

Notes:

  1. The system boundary delimits the system as it shall be after its implementation and deployment.
  2. At the system boundary, the external interfaces between the System and its Context have to be defined.
  3. 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).
