If the problem is not defined clearly, it’s that much more difficult to get a solution. For how do you solve that which you cannot identify as a problem?
I relearnt this when looking at my research. What is it that you are trying to address, for it is only the question that will guide the exploration.
Yes, there are times when you’re not solving a definite problem, merely looking at discovering new territory. For the rest, better reframe the question until the problem is clearly defined.
