I've never seen a business function properly where there are management consultants involved.
Over the past 15 years I have worked in 4 companies. The only profitable business was one managed by people who had been merchants and businesspeople their whole life. They had no management consultants in the business and refused to employ people who were ex management consultants.
The other businesses I worked in had a plethora of management consultants spouting graphs, flow charts, and theories every meeting you could think off. All of them went bankrupt eventually. They had people running the business who had no idea how to make money if it did not involve invoicing clients for reports or analysis.
Rod your company of management consultants, and those who have worked as management consultants and you will find profits will start to emerge.
