I was watching a video about UHC and the DDD strategy, and they mentioned that McKinsey was the consultants that really introduced these strategies to the health insurance industry.

In the intro to his book, Feinman wrote that insurance companies began to significantly reconsider the claims process in the 1990s when they "became a profit center rather than the place that kept the company's promise."

A major part of this shift occurred when insurance companies, including Allstate in 1992, hired consulting giant McKinsey & Company, he said.
