In this book, the author points out that anyone who performs a management function, must have some reliable method of adding value to the products and services of the organization. One way to do this is by properly understanding and using Design of Experiments (DoE). This book is not a DoE text. The main emphasis of the book is to expand the horizons of those who manage, in order for them to see new possibilities of adding value themselves, and of managing value-added operations. It shows how to use this versatile, effective and efficient tool in applications beyond traditional manufacturing and design engineering and how DoE can be used as a unifying theory throughout an organization. This book should be of interest to practising industrial and manufacturing engineers, quality professionals, senior undergraduate and graduate IE students, and MBAs.
