But refactoring for the sake of refactoring - or just to get a shorter method/function body can easily led to just the oposite, as I have sadly seen way too often.
A perfectly sane 400 line function/method stuffed with comment of a process that was a sequential series of logical steps that only got interrupted by serious Exceptions/dies was broken into several parts shattered across modules without proper call-checks and, worse, rewritten in an understanding that was not true, thereby killing the whole process.
Some people say they understand code better when it is rewritten into smaller chunks. That might (very) well be true if any of those chunks is to be reused or makes a perfectly sane unit. If the code however is not (ever) to be shared or reused by other parts, refactoring just because of size most of the times leads to serious errors. At least in my experience.
