Question

9. As a systems analyst, discuss how the concepts of decomposition, modularity, coupling, and cohesion can be applied to a car as a system.

Answer 1

Decomposition is the way of dividing a system into smaller components.
Car is a complex system having various components i.e engine, gear box,
brakes, clutch, accelerator, driving wheel, ignition, battery, fuel tank,
front dashboard etc.

Modularity helps system in managemement of it's components into modules
or by grouping certain components uniformly.In car engine, ignition system
and gear box work in modules.

Coupling handles the interrelationships among components and modules for the
system better performance.Car to function properly requires engine works in
tandem with gear box, brakes, accelerator, fuel etc.

Cohesion is a measure to depict how independently a module or a component can
work in the system. In car the brake functionality of stopping car is independent
of any other component similarly module of engine and gear box functionality of
controlling speed is independent.
