> Do you really think it’s impossible for a manager to rate a commit
if the manager is able to know how long something would've taken, it is because the task is simple and already well specified. Therefore, the work will be similar to delivery analogy from the OP. I do believe some places (such as oracle) do this sort of rating (heard from the grapevines).
However, most work i find that require a developer isn't simple tasks, but complex cognitive thinking to come up with a solution. I dont believe a rating system works for such work. Peer judgement, as well as long term results (such as a stable, working system that expands as required in a timely manner) work much better. But by the time the long term comes, the developer's contributions would've been diluted if the team expands massively due to success, or have moved on!
You are misunderstanding. They are not suggesting this would be a good or objective system. The problem is that ratings for drivers/deliveries/restaurants are just as arbitrary as this. I have seen people give 1 star reviews to a restaurant saying that the food was extraordinary but the waiter told them that it is possible to tip by card without them asking.
