Answer:
Using the archetype can help us understand the character and writer to introduce it faster to the audience
Step-by-step explanation:
When introducing the character, the audience that is consuming the media can more easily and clearly recognize what is already familiar to them.
In that case, we can easily understand the character that is already bit known to us, the one based on previously used archetypes, which makes it quicker and easier to add up to that character and develop it faster and more understandable.
For example, if the writer wants us to understand the character is loving, caring, wants everyone to be fine, cherishes family and want them to have strong connection to some other character they will write it as a mother to that character, Archetype of the mother in our culture is sweet, caring person that has unconditional love for their children and usually very caring nature in general. Writing this character as a mother makes the audience understand it faster, develop a fast and familiar relationship with them. The writer doesn't have to have a complicated starting description to this mother character but can start with what is known and instantly start developing the rest of the character along with the story.
