The book is very thorough, covering everything from the basics of visualizing data (histograms, box plots, etc.) through basic DOE and SPC all the way to more sophisticated SPC concepts such as narrow-limit gauging, acceptance control charts, and cumulative sum charts. I cannot think of a topic in basic SPC that is not covered in this text. A great bonus is the CD that comes with the text that includes answers to all of the exercises and an add-in for Excel that performs Analysis of Means, making this great graphical tool for summarizing results of statistical analyses even more practical to use.
All in all, a very thorough text with many examples/case studies that would be useful to anyone in industry in charge of controlling and improving processes.
When I first got a job in Quality Assusrance, this was one of the books I consulted in my local college library. I soon found it was the best of the lot for its clear explanations, practical examples and sheer readability. When I came back into QA after working in another field, one of the first things I did was procure a copy of the book from a bookfinder - the 2nd hand copy I was delighted to discover also had Ott's signature!
It is great to see an updated edition is now on sale and that Ellis Ott's name is not forgotten, for he (as far as I can find out about him) is one of the unsung pioneers of Statistical Process Control. Ott is not longer with us, but the co-authors have sensibly decided to update a classic, rather than starting from scratch. The examples in the older book are as relevant today as they are then.
From what I can see, this book sticks to the philosophy of the earlier editions but has modernized its approach in some respects, especially in the notation of Experimental Design and in the use of Excel, which I also remommend as an easy-to-use PC tool. Highly recommended for practitioners of Statistical Process Control.
The book is divided into three sections: Basics of Interpretation of Data, Statistical Process Control, and Troubleshooting and Process Improvement. The first section reviews many basic statistical concepts familiar to most statisticians. The second describes many facets of SPC some of which, such as Precontrol or Narrow-Limit Gauging in Process Control, the reader including myself may not be conversant, but will find useful in their own line of work. The last section describes what are probably underutilized but often very useful troubleshooting techniques. ANOM, for example, is a powerful way of analyzing data from industrial experiments with two or three factors resulting in graphics that can be used to clearly communicate conclusions to managers, to other engineers and scientists, and/or to operators on the shop floor.
I really enjoyed reading this book and am finding it to be a valuable reference to which I refer again and again.

That little passage suggests that, though he may be an excellent diarist, Ellis must have been a lousy reporter, one completely lacking in the objectivity supposedly required by the
profession. If Elvis had had access to Ellis' diary, he might have answered Ellis' question with a question of his own: "How can YOU justify asking ME that question when you did not ask it of Grace Kelly, who not only acquired enormous wealth in her acting career, but married into more millions by bagging Prince Rainier of Monaco?"
Ellis interviewed Kelly in 1956, an experience detailed in his entry of January 11 that year. His questions to her are never more challenging than this one: "Will you see the prince today?" (p. 232) Ellis didn't ask Clark Gable's widow how her late husband justified the millions he made when school teachers were underpaid, nor did the reporter grill composer Irving Berlin on the matter either. Apparently it was alright for Kelly, Gable, and Berlin to make millions because Ellis appreciated their "talents," but Presley and rock and roll didn't pass muster with "America's Greatest Diarist," as Ellis is called on the jacket of his book, and, therefore, it was wrong for Presley to strike it rich. The question, if it was worthy of being asked at all, should have been directed at a society that values performers more than it does the teachers in whose hands our children's education is placed.
That being said, Ellis' book is a worthwhile read for anyone interested in fine writing and a purely subjective (and, as noted, sometimes hypocritical) account of life as it was lived and observed by Ellis in the 20th century.
The book has excellent illustrations, paintings, and photographs, and biographies of several prominent shark researchers, conservationists, and shark-hunters. But more importantly, this book does a good job of summarizing aspects of the biology, ecology, and evolution of this amazing and intruiging group of animals.
Is this "the" definitive shark book? I would say that's a safe statement for the non-technical crowd. The only thing it needs to keep the technical crowd happy is a comprehensive list of references to scientific literature that was used to provide the information detailed in the book.
If you are interested in marine life, and in the lives and times of this group of top predators, then this book is for you.
Top marks, even though some of the information is becoming somewhat dated.
