The Management Myth, by Matthew Stewart, is a harsh look at the management consulting industry. Stewart, a philosopher by training, took a job with a management consulting firm created by former McKinsey associates. His book, which began as an article in The Atlantic three years ago, describes the history of management consulting starting with Frederick Taylor and Elton Mayo and ending with gurus Tom Peters and Jim Collins.
It's tough reading if you're sold on the value of management consulting. The book is probably a lot more enjoyable if you've been on the receiving end of some new consultant-led management fad imposed from above by an unwary exec.
