Donald J. Wheeler – Understanding Variation: The Key to Managing Chaos, 2nd edition
We live in the “Information Age”, and much of that information comes to us in the form of numbers. Unfortunately, “information is random and miscellaneous, but knowledge is orderly and cumulative.” Before information can be useful it must be analyzed, interpreted, and assimilated. This process of digesting data has been widely neglected at all levels of our educational system. Individuals come out of their educational experience knowing how to add, subtract, multiply, and divide, yet they have no understanding of how to digest numbers to extract the knowledge that may be locked up inside the data.
This deficiency has been characterized as numerical naivete. Numerical naivete is not a failure with arithmetic, but it is instead a failure to know how to use the basic tools of arithmetic to understand data. Numerical naivete is not addressed by the traditional courses in the primary or secondary schools, nor is it addressed by advanced courses in mathematics. This is why even highly educated individuals can be numerically naive. Fortunately, the cure for numerical naivete is very simple. The principles are easy to grasp, and the techniques are very easy to implement. The use of the techniques presented in this book can have profound consequences both for individuals and for organizations. These techniques have been thoroughly proven in over 70 years of practice in all walks of life. This book will tell you how to overcome numerical naivete. The real world will give you the opportunities for practice.
