A design system can be meticulously organised in Figma yet leave questions unanswered when it reaches the product. That is why I check whether its tokens, components and states also explain the decisions the code needs.
In Buy&Sell I wanted to check something specific: that the system’s visual states corresponded to the product’s permissions, data and lifecycle.
Design contracts, not catalogues
A useful component is not the one with the most variants. It is the one that expresses an understandable contract: what it receives, what it returns, which states it supports and what can change without breaking the whole.
Figma helps us explore and align. Code demands precision. When the two diverge, fixing pixels is not enough: the shared model needs to be reviewed.
Handoff is a conversation
Documentation does not replace collaboration between design and development. A resilient system includes decisions, examples and limits, but also a process for negotiating exceptions.
The fidelity that matters is not whether two screenshots match. It is whether intention, hierarchy and behaviour are preserved when the product receives real data.
