McKINSEY & CO. by Clayton M. Christensen

“At highly successful firms such as McKinsey & Company, the process and values have become so powerful that it almost doesn’t matter which people get assigned to which product teams. Hundreds of MBAs join the firm every year, and almost as many leave.

But the company is able to crank out high-quality work year after year because its core capabilities are rooted in its processes and values rather than its resources.”
