Product Monday: The Google Calendar A/B Test

Apparently Google is testing a new design for Calendar Web.

Base
Variant

The most obvious changes are the font, using round instead of square corners for calendar entries and buttons, new iconography, and adding week number on any monthly view.

It seems similar to the recent changes in Keep. And it all seems like making it more “Material Design” like.

I wonder what is the metric for such a test. I can’t think of an obvious one. It is an enterprise product, so retention is tricky as the buyer is not the user and in general it is not easy to switch productivity suites.
