Measuring the Impact of a Design System
“My gut feeling was that there was clearly a reduced amount of work in the team for the UI engineers (I am one of them), and that this was caused by the fact that we were not continuously writing new CSS at every new feature, but we were able to re-use and simply combine (“like Lego”) the existing UI components provided by Cosmos. And that this was also caused by the fact that also the mockups provided by the designers were more consistent, and followed a set of pre-defined patterns, so building UIs for us had become increasingly simple and straightforward.”
Really interesting look at a way to measure the reduced work load that comes when you have a well functioning design system in place. This wasn't the easiest thing to chart, but the results are stunning and amazing.
