This update by Joseph P. Ficalora now ties in Six Sigma to Louis Cohen’s classic text on Quality Function Deployment (QFD)—the process of converting customer wants into engineering targets. Ficalora, president of global services for Sigma Breakthrough Technologies, delivers a textbook-sized volume. However, it is written in a first-person point of view using action verbs that makes for easy reading. The text is also spiced with anecdotes from the author’s own experience. Meant to satisfy multiple aims, the author divides the subject into five parts, from covering a brief history and basic concepts to a detailed handbook for deployment. There is also a section on extending QFD. If you want a deep knowledge of what QFD can do, read the entire book. However, do not expect it to yield all its secrets in a single weekend read. The subject is deep and the book reflects that.
