First and foremost if you must structure a problem you must first identify the problem. Then after structuring comes in, now how do we structure this already know problem,
Knowing that structuring is like breaking down a problem into a more manageable one of which each of it can easily be analyzed .
A structure can look like a tree , or even a set of bullet-points with several levels of sub-bullets.
Structuring is helpful at all the stages of problem solving process, it helps split the work into pieces which is used as a guide to data collection and generation of hypotheses.

When these hypothesis are being put to testing if they bring solutions to our problems then they become theory if otherwise further hypotheses are tested.
Finally problem structuring helps bring us closer to our solutions.
