My thought exactly. I am convinced M$FT resists implementing QC procedures. Probably because proper QC can delay a product's introduction."I know, I know. Just skip the rigorous QC for now. Give it quick once-over. We gotta get this thing out the door or there's gonna be hell to pay. Don't worry, we'll do the QC later and stick it in version x.1"
I'd bet a dollar statements like this are made around M$FT on a regular basis.
They do not, much to their detriment, realize that QC is not a "separate" process; rather it must parallel the development process from the beginning.
