I told my team I couldn't carry on as we were, and I had no idea what the alternative was.
For most of my career I believed a leader earns the right to raise a problem by arriving with the answer attached. Bring solutions, not problems. Following that rule kept me quiet for months at a time.
Eventually I hit my limit. A working arrangement had stopped functioning, I could see that clearly, and I had nothing resembling a recommendation to put beside it.
So I said the smallest true thing available to me. I can't carry on like this, and I don't know yet what the fix is.
Almost everyone else had reached the same conclusion long before I opened my mouth. They were waiting for someone to spend the social capital first, because whoever names the problem carries the risk of being seen as the difficult one.
We worked out the answer together, and it was better than anything I would have arrived with on my own.
Naming a problem you cannot solve converts a private worry into shared work, and the shared work is what produces the answer.
If you are carrying something you cannot fix yet, say it anyway. You are almost certainly not the only one holding it.
