As a design system team of a multiple vertical products app, our coded components is widely used by a lot of verticals frontend engineers everyday which we found there's a findability and information display issue when they wants to find out the components information and capability through sample app.

I conduct a primary research to vertical frontend engineers and QA and improve the sample app user interface in order to make sure they can easily use design system component easily on their workflow. Expectedly it will reduce # of defects and increase engineers productivity rate
