> somebody said that a thing is simply not possible and a manager asked "but what if it was possible?"
I've been an Individual Contributor, and a Manager, and am back to being an IC.
I've been on both sides of this conversation.
One of the benefits of being a manager is being able to see the forest from the trees while your team members may be so focused on their tasks they do not see the big picture.
Sure, sometimes the answer to "but what if it was possible?" if just "it's not."
But a lot of times, the good managers I've had would propose an approach to MAKING it possible that I just simply didn't see. And I've been able to do the same in their shoes.
Sometimes it requires a paradigm shift -
Q: "How do we get to the other town faster?"
A: "The horses are running as fast as they can"
Q: "What if we found a faster horse?" (e.g. a car)
But honestly in day to day office culture it rarely needs to be so revolutionary -
Q: "Could we finish the project faster if Bill's team helped us?"
A: "No, it's not possible. Bill's team said they are completely swamped"
<Goes off to do some managerial work>
Q: "Okay, I've chatted to Bill, and his team is fully available to help us finish the project."
