Immeasurably great
If you are allowing your metrics and analytics to drive your product design and your feature development, you’re doing it the wrong way around.
Adequate design, that fits the business’ needs, comes directly from measured actions and events.
Those analytics.
Those metrics.
Good design, that fits the customer’s needs, come from communication with, and direct observation of, your users.
Great design?
The great design that makes your users say “Wow!”?
Great design comes from your designers.
And I’ll be damned if you can ever prove to me that you can measure that.
