This book is the result of a study that has been ongoing since 1997.
.
In this book, I tried to provide information for all managers in general, but especially for those who are new to management and management candidates.
.
The information in this book is composed of what I have experienced, seen, heard, heard, read and thought.
In other words, my own experiences and the experiences of others came together to create this book.
I hope it will be useful to everyone who reads it.
