I can’t find the appropriate term to express something that one can try in order to fix a problem, but that is not guaranteed to work and might even lead to wasting resources.
The word “solution” seems inappropriate since it entails that what I will try is going to work. It has a positive connotation I believe.
Here is an example sentence with a context for the word I am looking for:
Methodology X was done in order to avoid wasting resources on unfruitful (insert a replacement for the word “solutions” here).
In this example, even the word “unfruitful” seems a bit awkward to use in a formal context.
I am looking for a word preferably used in scientific journals and other academic publications.
