I teach business analysis (UMN Carlson School of Management) and am looking for a few good (short = 2 - 10 minutes) videos to enhance the lectures.  We cover the usual topics (business case, requirements,   process modeling, data modeling, test cases, etc).  I'm particularly interested in those that show BAs describing their real life roles or demonstrating good requirements gathering techniques, though short videos on other relevant topics are welcome.

I've done a basic search on YouTube and have found it tough going (e.g., reviewing video after video), so I thought I'd check in and see if some of you might have some suggestions.

Thanks for any help that you can provide.
