I have seen mathematically formal methods used successfully on industrial projects involving more than a hundred engineers and thousands of person-days of effort. I have seen formal proofs carried out on safety-critical metro systems by industrial engineers at Siemens Transportation and on the message choreographies for electronic commerce systems by software engineers at SAP.

In my opinion, the larger and more complex a system is, the more it requires the use of abstraction to master the complexity; abstraction without formal logic is just arm-waving.
