Nobody with any technical competence is inviting a place like McKinsey in the first place. Because of course not. Unfortunately McKinsey is quite happy to talk a big game and sell sub-par technical services to their customers who are either too dumb or too craven to see through the charade. Same goes for big-4 technical consulting in my experience, but less extreme.
