At first, when I updated this book (which was written for engineers), the people who reviewed my manuscript commented that the advice in the book would apply to anyone who is working, not Only for the intended audience. The book was first published in 1944 under the title The Unwritten Laws of Engineering, and has become popular ever since, but mostly among engineers. and executive. Some readers recommend that the book be open to a wider audience. However, in 2001, we decided to update the book without changing its size and style.
Although I revised the key parts of the book in 2001, I still try to make these changes as difficult to recognize as possible. Most of the amendments are in response to changes in social values, in employment law, and in corporate structure; All things have evolved over time. I do not regret not mentioning the latest technologies (e-mail, computers, Internet), the advice in this book goes beyond simple devices at work. Although some words and phrases have been changed because they are so ancient, there are still many classic words that are kept - they will make the book more fun.

What I didn't understand until recently was that this book is also suitable for everyone who does business. There is no need to correct much for these rules to meet a wider audience. In addition to replacing the word "engineer" with "businessman," this print version changed only slightly from the previous version.
