You've hit the nail on the head with your reference to performance support. I wear the instructional design hat for a retail company and I can say that I have shifted my focus from creating courses to creating job aids and other performance support tools. Currently I am working on a Wiki rather than focusing on designing some new course. As the purse strings tighten, corporations will be looking for low cost solutions that pack a punch and performance support is the answer. This really strikes a chord with me as I just finished "Job Aids & Performance Support" by Alison Rosset this morning. It's a good read for those interested in this topic.
