Design Systems are very popular in organizations right now. They typically are used for a consistent component library across products in an organization. I've read that cross-disciplinary teams can benefit from the design system. However I cannot find actionable examples of a marketing team benefitting much from a design system.
Some design systems touch on voice & tone, typography, color but the components that are used for the product typically wouldn't be all that beneficial for digital marketing ads. The Button component for an app isn't always applicable to marketing materials.
Similarly, I imagine outside of colors, typography, principles etc. design components for the products aren't the same for the company's website. However, you could make an argument to build a different component library for the website. Sure it may use some similar components but I typically have experienced websites are distinct from their products. Example: An email input sign up isn't always the same input as the input field found in a product.
When reviewing Google Material's design system on textfields I went to gmail.com on a Desktop browser to do a search and their textfields were actually different from the textfields in their guidelines. The Google Material textfields have curved edges and can be filled our outlined. Their outline has borders on all 4 sides. Gmail.com on a browser has a bottom border only for their search form. Which I think looks better for a browser based form. This has me wondering if another design system would be typical?
So is a whole other system that borrows from another system typical in an organization? Or does one design system typically cover instances across not just product but marketing and web? I imagine at the very least a different component library may be necessary but I've never seen this I'm unsure what is common and I'm looking to hear from anyone with experience to give this clarification.
