If the authors’ experience could be summed up, the book would contain 50 years of practice and theories learned through hundreds of books and academic studies.
The book is addressed to anyone who want to continuously improve processes, people or himself. The keynote when writing the manual was to encourage reading not only executives and middle-level employees, but most of all employees directly supporting processes – because without them no improvements are not possible.
