This should be the core of any product company. Product companies tend to focus more on growth, while forgetting that their product is actually used by people for people-tasks. While it is often assumed that user growth or certain activities growth equates to user happiness, this is not necessarily true. In my usability studies I have found multiple instances the data said everything was fine, but user tests showed the users were unhappy. How much exponential growth are we losing by not realizing it could grow much faster if we brought user joy in the first place.
Metrics are awesome, but user research, user studies, market research and testing are all forms of data, albeit qualitative, that can add clarity and details to otherwise quantitative data. Both together are a beautiful artwork that shows the complexity and wonder of how truly people use your product.
