> proper testing and documentation is the first thing that management wants taken out of the story
That's not breaking down a story into smaller stories though, that's simply not doing some of the tasks necessary for a story to be complete. "Story" is not a synonym for "task"; a story is user-centric not about internals. "Write the documentation for this feature" is not a story and "write the tests for this feature" is not a story, they should be part of your definition of "done".
