Acronyms have a useful role among specialists. They allow quicker and more succinct communications among specialists - think texting for geeks. However that is only useful when those specialists are in the very same narrow field of specialty. If they are not within the same very narrow field, I find that it causes more confusion than necessary.

So, as a good Project Manager, it's my job to decode the acronyms and put them in plain descriptive English for the other specialists. And yes, I sometimes have to put up with the "don't you know anything?!" look, but, hey, that keeps me humble.

It IS a big universe out there!
