"British Management" is an oxymoron.
Had one a while ago paid over $250,000 per annum who said "OK chaps, my management style is suck it and see. If one thing doesn't work I'll try something else".
Normally for $250,000 you actually have to know how to manage.
British engineeers are great - witness the Range Rover, however British Management then sat on its hands for 20 years while the rest of the world caught up. They did the same with the mini.
