If you want to do a self assessment on your analyst skills against the BABOK I just published a slideshow on slideshare.  You can access it via the better projects blog and either just read through and think about your skills or download and print it up for use as a workbook.

If you use it please comment here on whether it was a useful tool and if you have any suggestions for improvement.

Access the slideshow here; http://betterprojects.blogspot.com/2007/10/ba-skills-and-knowledge-audit.html

I found this helpful when filling up the application form for the CBAP exam.
