How do you become a system engineer?
Gain practical experience:
There are various ways to gain experience and a whole system understanding even before you start practising.
(read on ..) ⤵️
One example is testing: System Testing.
This may also be a very good entry portal into Systems Engineering. When you are testing a system you will
-Understand how it's put together and how it works
-What are its functions at system level, after it has been integrated ↓
-You already got a grasp on what emergence is and how it could be undesired.
-Understand noise factors, robustness and the system performance in hostile environments.
The next logical step is to move into Systems Engineering to work design systems better than those you tested.
