Management consulting (sometimes also called strategy consulting) refers to both the practice of helping companies to improve performance through analysis of existing business problems and development of future plans, as well as to the firms that specialize in this sort of consulting. Management consulting may involve the identification and cross-fertilization of best practices, analytical techniques, change management and coaching skills, technology implementations, strategy development or even the simple advantage of an outsider's perspective. Management consultants generally bring formal frameworks or methodologies to identify problems or suggest more effective or efficient ways of performing business tasks.

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.

Management consulting has grown quickly, with growth rates of the industry exceeding 20% in the 1980s and 1990s. As a business service, consulting remains highly cyclical and linked to overall economic conditions. The consulting industry shrank during the 2001-2003 period, but had been experiencing slowly increasing growth since. In 2004, revenues were up 3% over the previous year, yielding a market size of just under $125 billion.
