Interesting. Any sense whether that system was consciously constructed? (Like, Task a group to generate product changes appealing to users, and then cherrypick the ones that are profitable, to get/maintain profitable good product.)
Or was it not as conscious, more an accident of following industry conventions for corporate roles, and corporate inefficiency&miscommunication?
It was extremely scientifically methodical. Everything is designed from UX and other sources of holistic research. Then validated with the most built-out AB test system you can imagine. Only winners are kept.
Meta is doing this thousands of times per month, all the time.
