I should be careful not to give the impression that, when one is stuck with a problem such as this, just trying out the OPMS will do the trick for you. NOT SO AT ALL!!!

OPMS could possibly "lead to" the 'open-minded' frame of thinking that could help, over time, to bring one to the kind of out-of-the-box thinking that could help provide the little insights that may help resolve the tricky problem under consideration.

But - at the same time - we have also seen that one has to be somewhat 'open-minded' even to try out the OPMS at all.

There seems to be some complexity here that may not be readily or easily resolved.

In any case, the advice is: DON'T try to use the OPMS to help resolve any problem of this kind. It is, in fact, contra-indicated.
