Subsystems

As systems become complex, they can be broken down into subsystems - smaller, more manageable components that perform specific functions within the larger system.

Characteristics of subsystems:

  • Encapsulate related functionality

  • Can contain their own interfaces and internal elements

  • Allow for hierarchical system decomposition

  • Help manage complexity through abstraction

Click the green circle on top of the interface.

The system will immediately turn white because we have transitioned from black box to white box analysis, looking at internals.

Each subsystem is itsself, a system, to be treated as an SOI. You'll be presented with element detail tab identical to the one from one we started.

Do the same for the other two interfaces.

Now ready to start connecting our subsystems, identifying how they interact with each other.
