I agree with Rolf regarding QA and becoming a BA supervisor. Still, I think it's part of a full time job if you're working in the same organization. Are there opportunities to work for another company as a BA supervising the work done by the internal org-units? I believe it's a little bit hard to put an external BA  to supervise the inside work when instead you can offer this position to one of your own BAs. 

The second point is one to follow :).

What about working with clients outside your city/country using collaboration tools like Skype, maybe an online modeling tool, video conference, etc. ? If users on this forum have this kind of experience, please reply this post.

Have a great day all!
