One memo that says, "Do this."
Add a bunch of MicroSofties that want stock options so they can be rich. How do they get stock options? By giving Uncle Bill what he wants.
Mix in 20-hour days.
Presto, secure products.
Hahahahahaaaah! That's some formula, but tired and whipped employees do not make better coders.
Try folding in some training, code inspections, testing and some mandatory security audits.
