Fellow Chicago.pm'er up on O'Reilly's site
Fellow Chicago.PM'er Andy Lester has this great little article on the O'Reilly Network site called O'Reilly Network: Process improvement on the sly [July 18, 2003].
At my last job, for a while I was a one man development shop and CVS was a lifesaver. Not only did I have a rich set of backups in case I lost (or a client deleted) some code, but a project manager or another developer could look in and get a history of the changes in plain language, not only in code.
Also, as a new convert to automated testing, Andy's first testing talk is a great introduction. I hope that he will put his recent OSCON speech up as well.
