I've had a print copy of this document on my shelf for a couple of years. I use it as a reference about a dozen times per year.
The NASA Software Engineering Handbook [1] is also full of interesting stuff. Unfortunately it's all in an incredibly slow Confluence wiki.
This document is delightfully (?) 90s-era MS Office coded, with plenty of clip art and word art. Somewhat funny to see.
For a rather dense document from 2004, is any of this worth casual study and still relevant?
