Example Airbus A320 Family.

Answer 10

System level 0 - Family:
A320 base model
A319 and A318 shrinked

Each variant has specific realization details that must be carefully documented.

Subsystem level 1:
every model has its adjusted subsystem (e.g. engine A320-111)

Question 11

What is the target of Configuration Management?

Answer 11

It ensures that it is clear how a product is currently configured and how it was configured in the past.
