Bumped into many management consultants over the years. Mostly they seem to be ex-managers who almost certainly lost their management posts through their own incompitence, but failed to realise this and still think they might be able to manage something. Only once did I come across a management consultant who was any good. He was working for a company I had some dealings with, and he wanted to talk with me as a customer of that company. That company were all very impressed with him after he'd worked with the for a month, and he was due to return for a followup session a few months later. Apparently he was booked up years in advance for new work, and turned down a good deal more than he took on.
