Is there a word or phrase for something that is meant to be a temporary solution to a problem, but because it gains enough momentum ends up becoming the permanent solution? Ideally the word/phrase should convey the idea that the temporary solution is less than ideal.
The closest thing that I could find was this, but it describes something that was intended to become permanent all along: is there a word for temporary-but-may-become-permanent.

(and the scheduling program was never heard from again; except in lamentations and wistful remembrances.)
The spreadsheet would be considered a ___ solution.
