established during system engineering activities? Describe
the characteristics, if any, and explain why a
consideration of them must be delayed until later
engineering steps.

Answer Posted / ketan korat
When putting a system together, the different components
interacting may show unexpected behaviors. It is hard to be
able to predict these completely.
A typical example happens in power plants when running steam
boilers or power generators in parallel. The load is not
distributed evenly, as would happen on a stand alone unit,
but needs to be constantly tweaked.
In addition, there are unexpected configurations resulting
from the installation itself, which create unstable modes
due to interaction. These must be addressed and proper
compensation through the control system be applied,
