Ask HN: Who at a company gets to decide if a team is moving fast enough?

I read 'Programmers At Work' early in my career. Gate's comment on a single bug indicating that there may be many has always stuck with me...

"Before I sit down to code something, most of the instructions have already run through my head. It’s not all laid out perfectly, and I do find myself making changes, but all the good ideas have occurred to me before I actually write the program. And if there is a bug in the thing, I feel pretty bad, because if there’s one bug, it says your mental simulation is imperfect. And once your mental simulation is imperfect, there might be thousands of bugs in the program. I really hate it when I watch some people program and I don’t see them thinking."

The person the team works for and who pays for it.

Now, sometimes the problem is to make that person understand that it is not possible to move faster and why.

Ideally, the team.

In practice, management and above.
