What makes a good management consultant and a bad management consultant?

Management consultants listen to the client and deliver.Management consultants listen to the clients questions and concerns that aren't being heard and encourage them to expand their thinking.

Great management consultants ask good questions to fully understand a situation before making conclusions.They're willing to explain their logic.When bad management consultants are asked for the reasoning behind their conclusions, they take offense and think their years of experience allow them to brief analyze a situation and prescribe a solution.
