Acronyms are like macros with undefined behavior during expansion, out of necessity they map as many-to-one and I've had cases where my internal expansion of what I thought was a pretty clear case ended up being the wrong one.

In our reports we use them but we make sure to define each and every one at the first use, and to add a wikipedia link or other external reference to give background, to avoid confusion and to ensure that a particular acronym isn't going to end up being re-used with a different meaning within the same document.
