scope:

There are many books on TWI, but they don't include any new material. Practitioners have altered the programs without understanding the underlying principles. These changes have made the programs less effective. This book will identify/explain the main principles of the TWI Programs. Knowing these principles will enable modification of the programs to fit organizations' needs/cultures without losing any effectiveness -- Practitioners will know what to change and how to make those changes. This book reviews WHAT the programs are and then explains HOW to use them. It tells WHY we do certain aspects of each program. When we know WHY we do something, we won't stop doing it for the wrong reason.
