A design system is a pattern library that serves as a single source of truth for design and code related components. Customers for design systems are: coders, designers and end users. The biggest advantage you gain when having a design system is offering consistency in quality, accessibility, reusability, inclusivity, reliability, etc.

What a Design System is not:
Accessibility is not only for people with disabilities. Accessibility is for everyone.
For example, you could make your apps in a phone more accessible by making them usable with one hand only, that can help people who carry their child on another arm or are simply busy holding something.
Words can also be accessibility, writing copy for your website with complex jargon can create a barrier to everyone who is not familiar with what’s being talked about.
The Web Content Accessibility Guidelines (WCAG) state that in order to be accessible, a site should be usable at 200% zoom. Some accessibility advocates state that this number is truly a minimum and many people with vision disorders need to zoom in much more than that.
It’s important that hand in hand with accessibility, you are also inclusive. When creating/developing/testing any form of media, it’s on your hands to raise your hand if you think something is not inclusive.
Keep this in mind, asking for feedback from minorities is not the only way to be inclusive.
