What helps in my experience is to Define Acceptance Criteria for your Problems.
That means, with some coaching questions you might be able to get a better and clear picture of the problem, and 2nd how do we learn that it is gone.
What you might ask and note down for the problem:
How do we know the problem has gone?
What effect do we see if the problem is gone?
Which metric would show us that the problem is away?
What would be a better state to be in?
What is the next target condition?
What is the minimal experiment we run to get as closer to a better state?
What is an action we can take that bring us close to the target condition?
A great thinking model is the Toyota Kata for this:
