I've read in this other question:
The Master's program (Software Engineering) I'm enrolled in offers both a thesis track and capstone track.
I'm somewhat familiar with the overall US academic system, but I've never heard of a “capstone track” before. I web-searched it, and found quite a few institutions that offer it, it seems a sort of more practice-oriented or business-oriented way of completing a given degree. It does not appear to be universal.
So: what is a “capstone track” in general, and how is it different from a Master of Engineering degree?
