Eisen Russell was a consultant of McKinsey & Company, and his clients included many well-known companies in the fields of finance, telecommunications, computers and consumer goods. Before joining McKinsey, the MBA from Wharton School of B-class University of Virginia was an equity fund manager and investment banker of Mercury Asset Management in London.

Founded in 1923, McKinsey is now the most successful strategic consulting company in the world. It has 75 offices and 4,500 professionals around the world. Perhaps it is not the largest consulting company in the world, but it is the most prestigious. Mckinsey is a famous brand in the international business circle, providing consulting for Fortune 100 company, American state and federal governments and foreign governments.

This book is divided into five parts. The first three parts focus on how McKinsey thinks and how to solve business problems. 1 3 is the essence of this book, from which we can get more things about career theory. The fourth part introduces in detail the great pressure that McKinsey people deal with in their lives. The fifth part briefly describes the experience and lessons in the company and shares some unforgettable memories of sales analysis with readers.

Part 1 McKinsey's way of thinking.

Chapter 1 Building a Solution.

The solution to the problem should be: based on facts, systematic and bold assumptions, and serious verification.

Be friends with the facts. Reasons: First, facts make up for the defects of intuition. The second fact can improve credibility.

Free use of MCE principle.

MECE means mutual independence and complete exhaustion, which is a necessary principle in McKinsey's problem-solving process.

The viewpoint formed by M 1ce principle is the clearest and most complete.

The application of M 1C 1 principle starts from the 1 layer of the solution, decomposes the problem (decomposes the large and complex problem into small and easy-to-solve subproblems), and lists the process list of the problem.

A good McCarthy question list and the number of first-level titles will not be less than two or more than five, and it is better to have three first-level titles.

Go straight to the solution of the problem, the initial assumption.

The original hypothesis is the third pillar of McKinsey's problem-solving process, and it is also the most difficult to explain.

Define initial assumptions.

Generate initial assumptions.

Test the original hypothesis.
