Only the most unflappable CEO or government executive can resist the siren call of a management consultant during a crisis. For about a century now, consulting firms have dangled a tantalising proposition in the face of the wretched and the weary of public and private administration: we’ll solve all your problems, make all your dreams come true, and then we’ll vanish, cradling our newfound, formerly confidential knowledge of your industry.
It’s a tempting bargain. So tempting that management consulting is now America’s biggest business-to-business service industry, with roughly $385 billion in annual revenue. But as appealing as the industry may be to business leaders, it is all the more attractive for the public sector, where managers need to achieve high levels of flexibility while confronting limited resources and medieval hiring processes. The beauty of bringing in management consultants is that you don’t have to hire or train new employees, or repurpose or lay them off when the project’s done. Consultants swoop in at the right moment with the right expertise, and then disappear.
In the US, consultants work with all levels of government. At the federal level, they play a central role in creating the intellectual capital that powers our government, earning $23.5 billion on almost 30,000 separate federal contracts in 2022. At the nucleus of this booming business is a small group of firms, which are far more significant for the consequence and sensitivity of the work they do than the number of dollars they make. These include Deloitte, Booz Allen Hamilton, and of course, McKinsey and Company.
Over the past 10 years, McKinsey has completed around $1 billion worth of contract work for the federal government, more than half of which was contracted by the Department of Defense. As a report from the Quincy Institute found: “This work has ranged from advising senior officials on developing technology for the Air Force and Space Force to evaluating the management of the F-35 program.” In the same report, we learn that McKinsey has for several years considered the Defense Department one of its top clients, and that one of President Trump’s leading assistant secretaries of defence worked for McKinsey both before and after his federal tour of duty.
The consequences of this line-blurring between public and private would be complicated enough if leading consultancies confined their work to the US. But they do not. While management consulting grew throughout the latter half of the 20th century to saturate the American private and public sectors, it was also spreading internationally on the promise of selling “American management knowhow” abroad. “Whether reorganising the Bank of England, Royal Dutch Shell, the Government of Tanzania, or even the World Bank,” writes business historian Christopher McKenna, “management consultants disseminated American management techniques throughout the world.” While management consulting had originated in the West, it came to be a valuable resource to business, organisations and governments everywhere — in East and West, market and command economies, democratic and authoritarian states.
As the consulting hydra has grown ever more colossal, with consultants embedded in most large organisations, consulting firms’ webs of allegiances have become ever more complex. Frequently, this leads to conflicts as fraught as those in George Orwell’s 1984, in which a single entity is advising both sides in an adversarial system. These conflicts are legally challengeable when a consultant shares one company’s proprietary information with another — a problem firms can avoid by assigning different teams to competing client companies. But the legal system cannot solve the broader conflict, whereby the same consulting firm stands to benefit if either team wins. It has no answer to what happens when one consulting firm advises both a regulating agency and a regulated company — to cite a recent example, McKinsey advising both the U.S. Food and Drug Administration and Purdue Pharma. Or when the same firm consults two competing companies, or two governments that are geopolitical rivals or even enemies.
One such conflict arrived in the halls of Congress a month ago, when US Senators Marco Rubio and Josh Hawley challenged McKinsey and Co. for its work with the Urban China Initiative, a think-tank based in Beijing. The Initiative published a report in 2015 entitled “The Trend and Impact of World Technological Revolution and Industrial Transformation”, a litany of recommendations for Chinese government officials and business leaders to aid in the implementation of the Chinese Communist Party’s (CCP’s) “Made in China 2025” industrial initiative. Rubio and Hawley, who obtained a copy of the report, noted that it aimed to support the CCP’s goals of “dominating other countries in cutting-edge fields”, ranging from cloud computing and big data to artificial intelligence, renewable energy and human genomic technology.
