This is 100% the why.
Idk what the answer is, but it is not 100% this. It’s too simple and satisfying of an answer to be true.
Make a metric a goal, work tirelessly towards that new metric.
Does it make the product better? Well, the product is already made- so it doesn’t make a difference.
It’s only software developers who think a product is never “done”- normal MBA thinking is “we have invested in R&D, now there is a product, how do we get as many users of our product as possible”.
That's all its been for the last few decades. Everyone is now "data driven" and "metrics oriented". That's a footgun - if people can game it, they will, and numbers don't say what people think they say.
