A few days ago I was writing my bi-annual review, and I was thinking of how I could include some meaningful metrics about the success of our design system in Badoo.

It is undeniable that in the last six months Cosmos, the name we gave to it, has gained a lot of traction: everyone is mentioning Cosmos, everyone is starting to integrate or adopt Cosmos, there are even jokes around that if you have a problem, any problem, just open a ticket for Cosmos and it will be solved.

But this is not a metric. It’s really hard to measure people’s happiness, or the impact on how people work (and think) in term of UI, or the teams’ efficiency and velocity in delivering updates and new features to the product, and more in general the effect of a change in a complex system like a big company.
