SAP's competition is laying off just like SAP is. In fact, every industry in existence is laying people off. This is why sales are down, not because of your manager or the guy across the hall whose sales are bad.
Go to Oracle's board, where layoffs have been going on for 2 years. Then go to every competitor SAP has and you'll find the same thing going on. And if you're really ambitious, go to Microsoft's board, Intel, Dell, and on and on.
Google it. Layoffs, layoffs, and more layoffs.
