Ethan highlights a classic case of the McNamara Fallacy—measuring adoption of design system components.
Whenever I confront a design system problem, I ask myself this one question that guides the way: “What would HTML do?”
HTML is the ultimate composable language. With just a few elements shuffled together you can create wildly different interfaces. And that’s really where all the power from HTML comes up: everything has one job, does it really well (ideally), which makes the possible options almost infinite.
Design systems should hope for the same.
A collection of collections, this is a directory of design systems, with the handy option to browse by component type. The blueprints section is still a bit thin on the ground, but likes the most useful bit—an in-depth dissection of individual compenent types.
I completely agree with Dan that when it comes to design systems, completeness is an over-rated—and even counter-productive—goal:
Some organizations seem to hold up the ideal that, once a design system exists, everything in an interface can and should be built with it. Not only is that an unrealistic goal for most enterprises, but it can often be a toxic mindset that anything less than 100% coverage is misuse of a design system at best or utter failure at worst.
Snook’s Law in action:
Big, flashy things get noticed. Quiet, boring things don’t.
There isn’t much infrastructure in place to quantify the constant, silent, boring, predictable, round-the-clock passive successes of this aspect of design systems after the initial effort is complete.
A lack of bug reports, accessibility issues, design tweaks, etc. are all objectively great, but there are no easy datapoints you can measure here.
There’s probably a Pace Layer analogy in here somewhere.
