Having studied Jack Welch for nearly two decades and authored four books on him, business journalist Krames argues that Welch should win the prize (if such a prize were offered) for the corporate leader of the century. As the title indicates, this is a compendium of the key elements of Welch's thinking on business, presented in an A-to-Z format. Given General Electric's ability to enter new markets and sustain growth, there is a lot to be learned from Welch. The book, however, does contain a number of flaws. With respect to Welch's philosophy of Six Sigma, key concepts such as root cause analysis, control charts, and Pareto analysis are mistakenly presented as if they are new and developed though Six Sigma. Overall, though, the book provides the most concise and complete rendering of Jack Welch's business initiatives. Recommended for general audiences and business collections..
