The use of components will allow the system to continue to work around any modules that have failed.

When a microwave button GUI breaks, it does not stop the operation of the entire panel. For instance

the start button is usually the first button to start malfunctioning on a microwave. However the other

buttons may work and allow the end user to use the microwave by using the custom operation buttons.

Components will also allow the programmer to branch out to other programs to perform an operation

without interfering with the other components.
