I will acknowledge a grudge against all things SMM up front, but this thing should be scorned.
If "PSP(SM)" is so great, what software did Watts Humphrey (the author) produce? Yes, I understand Humphrey died in 2010, but people put out GPL software even back then, and it has survived to the present day.
The other outstanding problem with PSP is that "quality" is never defined. Without a definition, "quality" cannot be measured, and the PSP is cargo cult ritual. If you think about it for 30 minutes or so, you can come up with some aspects of "quality", but some will be in tension with others: speed-to-market is certainly in tension with "bug-free", for example. There's no way to resolve this tension in PSP, so it's pretty much useless.
The closest I found to what "quality" means in the first chapter of the document is: "When engineers use the PSP, the recommended process goal is to produce zero-defect products on schedule and within planned costs."
Zero-defect and on schedule. Wonderful. Let's take all the fun out of a job by trying to reduce it to chickens pecking on bells. Also, probably not possible. See: http://scribblethink.org/Work/Softestim/softestim.html
