Brief
As company went through many designers and revisions, each end uses its own system with many differences, causing a lot of communication costs. How to start unifying into a same language? Take color system for example:
Consider Accessibility : Color Contrast
Pay attention to color contrast especially for platform mainly based on dark theme
We as a designer have the obligation to make sure the product is as inclusive as possible. We distinguish between words for reading and words for decoration, and we made the rule that words for reading must meets WCAG standard.
Migrate Plan & Guideline
Plan the process and clearly define use cases in Design Guideline
The goal for guideline is for future maintenance, but besides that, I do a migrate plan to tell Dev what are changed and how can they apply the new one.
Brand Storybook : We(PM/UX/Dev) are all connected together!
Learning
Different from building a design system from scratch, this is an existing product. Creativity is not the key, and it is more important to find the balance between rules and flexibility. As a designer, we need to find the vocabulary that belong to this product.
