Management consulting is becoming more prevalent in non-business related fields as well. As the need for professional and specialized advice grows, other industries such as government, quasi-government and not-for-profit agencies are turning to the same managerial principles that have helped the private sector for years. 

An industry structural trend which arose in the early part of the 21st century was the spin-off or separation of the consulting and accounting units of the large diversified professional advisory firms most notably Ernst & Young, PwC and KPMG. For these firms, which began business as accounting and audit firms, management consulting was a new extension to their business. But after a number of highly publicized scandals over accounting practices, such as the Enron scandal, these firms began divestiture of their management consulting units, to more easily comply with the tighter regulatory scrutiny that followed. In some parts of the world this trend is now being reversed where the firms are rapidly rebuilding their management consulting arms as their corporate websites clearly demonstrate. 

Rise of Internal Corporate Consulting Groups 

Added to these approaches are corporations that set up their own internal consulting groups, hiring internal management consultants either from within the corporation or from external firms employees. Many corporations have internal groups of as many as 25 to 30 full-time consultants. 

Internal consulting groups are often formed around a number of practice areas, commonly including: organizational development, process management, information technology, design services, training, and development.
