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.
