I started browsing the book, as is my habit whenever I buy a new book, with the idea of doing an in-depth reading later. But, the subject matter is so vividly covered, I could not. Here is a book I could not keep back until I completed the first 4 chapters in my first reading itself.
It all started with the modern definition of quality as stated in the book "Quality is inversely proportional to variability". This definition, later led me to explore more into six sigma concepts to reduce variation before getting to ISO registration by any company. Nothing can be truer than the fact or statement in the book on ISO registration that "many quality engineering authorities feel that ISO registration is largely a waste of effort". I am one among them.
This kind of striking information, style of presentation, and the font type are so good that they tempt you to explore more into the book.
I enjoyed the 2-page info on legal aspects of quality, notes on Average Run Length (ARL) and was amazed by the fact that even an in-control process will go out-of-control automatically after 370 samples /observations due to the fact that 3sigma control limits
comprise only 99.73% good items.
Another area I liked most is the Hypothesis testing of assumptions or conditions in quality improvement situation.
Not many books explain so well the Confidence Intervals (CI) and Hypothesis testing.
When I read further into this Montgomery's work on "Introduction to Statistical Quality Control", I was doubly happy to have at last a solid book on SQC.
It so happened that when I started underlining some important points (that is the respect I give to good books), I had to underline almost all of the pages in his book (Not overdoing).I am sure, so will you do.
I plan to add more interesting areas, in stages, from this book that I liked best as I re-read and as an honor to such a great Author.
