i totally agree, i was being overly terse. To me, if something is working well then you should do more of it but, yes, you have to manage risk and see the whole picture. Like everything, it's a balance.
It's counter intuitive but in downturns consulting can tick up. The first place companies go to look to reduce cost is headcount but the work still has to get done. In come the consultants to implement a new system to increase efficiency and reduce headcount (it rarely turns out that way though). Also, I think it's easier to finance money for consultants than FTEs because of where the expense falls on the accounting books.
