How We Rebuilt Our Navigation

A design system is a set of decisions you no longer have to argue about. Consistency is kind, but clarity wins when the two disagree. We removed three options and support tickets dropped by a third.

A small example

A design system is a set of decisions you no longer have to argue about. An error message should blame the system, not the person. Whitespace is not empty; it is doing the grouping for you.

The prototype answered in a day what the meeting could not in a month. Contrast is not a style choice; it is whether people can read the page.

Trade-offs

A design system is a set of decisions you no longer have to argue about. Labels above fields beat clever placeholders every time. We tested with five people and found the same problem four times.

• Design the empty and error states
• Test with real data
• Start from content, not components
• Write the microcopy before the mockup

Lessons

We tested with five people and found the same problem four times. Users scan, so headings carry more weight than paragraphs. Contrast is not a style choice; it is whether people can read the page. Dark mode is a second palette, not an inverted first one.

Motion should explain a change, not decorate it.

Good defaults are the design most users will ever see. A design system is a set of decisions you no longer have to argue about.
