Internally the prioritized output becomes the meta work, not what reaches customers. What reaches customers is almost some kind of accidental byproduct of what the vast majority of people in the org spend their time on day-to-day.
My past experience is dominated by startups. The fake work I'm incentivized to spend time on would have been fire-able levels of misplaced priorities / waste everywhere else I've worked as an IC developer.
I've never worked for Apple, I'm assuming this pattern plays out everywhere at this scale.
