McKinsey & Company

McKinsey & Company (informally McKinsey or McK) is an American multinational strategy and management consulting firm that offers professional services to corporations, governments, and other organizations. Founded in 1926 by James O. McKinsey, McKinsey is the oldest and largest of the "MBB" management consultancies (MBB). The firm mainly focuses on the finances and operations of their clients.

Under the direction of Marvin Bower, McKinsey expanded into Europe during the 1940s and 1950s. In the 1960s, McKinsey's Fred Gluck—along with Boston Consulting Group's Bruce Henderson, Bill Bain at Bain & Company, and Harvard Business School's Michael Porter—initiated a program designed to transform corporate culture. A 1975 publication by McKinsey's John L. Neuman introduced the business practice of "overhead value analysis" that contributed to a downsizing trend that eliminated many jobs in middle management. McKinsey publishes a business magazine, the ''McKinsey Quarterly''.

McKinsey has been the subject of significant controversy and is the subject of a criminal investigation into its business practices. The company has been criticized for its role promoting OxyContin use during the opioid crisis in North America, its work with Enron, and its work for authoritarian regimes like Saudi Arabia and Russia. The criminal investigation by the US Justice Department, with a grand jury to determine charges, is into its role in the opioid crisis and obstruction of justice related to its activities in the sector.
