The 20th century saw the rise of American economic dominance and the birth of modern management. One firm – McKinsey & Company – did more to shape American business and influence global commerce than perhaps any other. From a handful of consultants in the 1920s to more than 10,000 at the turn of the 21st century, McKinsey is an undeniable success story. Organizations including Fortune 500 companies and national governments have sought its advice for almost 100 years. Yet behind the successes are guarded secrets involving catastrophic failures, disastrous recommendations, fraud and even jail time for its leaders. Journalist Duff McDonald’s balanced, penetrating account of McKinsey’s extraordinary achievements and spectacular failures can be repetitive, but still reads like a thriller. getAbstract recommends this century-long tale of ambition and hubris to business leaders interested in strategy, HR VPs seeking insights into talent management, and to all consultants.

In this summary, you will learn

  • How McKinsey led in the development of an industry and profession,
  • How it shaped American business in the 20th century, and
  • How the firm achieved remarkable success over a long period despite significant setbacks.

    Ahh the getAbstract really tickled my curiosity and need to know the detail. Not only from the way it is written but because McKinsey has been featuring very prominently and most negatively in the South African news over its corrupt dealings with our government. Having worked with them on some projects in my previous life I recognise some of the behaviours and a lot more makes sense now that I know how they hire consultants and have better insight into the business model. Could one They this is almost like a business cult? Embraced by business and sometimes just for the “prestige” of association? One thing is clear though McKinsey leave a trail of destruction in their path. They thrive on being proactive in the advice they give much against the better advice of those in the know. By the time they have been paid to repackage institutional knowledge and resell to those very organisations it’s sadly too late.
