Space on my office desk is not infinite and I only keep the most useful books within arms reach there. Other titles, often helpful but not useful on a daily or weekly basis, get relegated to the bookshelf along with all the vendor catalogs and old college textbooks. The Quality Toolbox is good enough that I made room for it next to my copies of Marks' Std Handbook for Mechanical Engineers and Machinery's Handbook.It contains a wealth of information that can benefit people at all positions within an organization, not just members of the QC or QA staff. It is laid out with a good graphical index in the front that aids you in selecting the right tool for the problem at hand. Each tool section, with the exception of the couple that deserve books of their own, has all the information you need to apply it to the problem and achieve real solutions, not just more paperwork. I found the examples of the tools being used on real world problems very handy at showing how the tools usage is not set in stone, or used in isolation, but adapted and combined with other tools to get answers.In today's highly competitive marketplace quality is something that is everyone's job, not just one group of checkers. This book presents information in a very "to-the-point" manner, with simple math when needed, that should allow a reader to make use of these tools all across their job responsibilities. This is the type of reference manual that should allow an organization to experience the benefits of putting quality at all levels and not just as an end checking process.My only suggestion/complaint is that a book of this size could really use the section scallops, or thumb index cut-outs, that would make finding the tool much faster. After deciding what tool you want to read up on from the index it does take more time than I'd like to actually get to the tool. A physical index with tabs or cut-outs would greatly improve an otherwise excellent reference manual.
