On the contrary, McKinsey is very well respected within the management consulting industry. It is part of the big 3 consulting firms: namely McKinsey, Bain, and Boston Consulting Group. The Mckinsey brand is probably the best known out of the 3.
McKinsey is certainly one of the best-known management consulting firms. As such there's plenty, positive and negative, that's been said about them (1). To cite but the best-known instance of the negative, there's their heavy involvement with Enron. Jeffrey Skilling, who used to work for McKinsey, is now in jail for his actions as CEO of Enron (2), and McKinsey consultants were heavily involved in running the company (3).
