THIS BOOK contains material used to train new engineers and technicians in a large manufacturing plant of a Fortune 500 company. It was not a company-training course. To the contrary, it was one engineer's attempt to get coworkers to document their work in a reasonable manner. Coworkers who attended my tutorial sessions went on to become effective technical writers. In my opinion, our department is the model for the corporation. Everybody finishes his or her projects with a report. There is a format for each type of document and a system for archiving these documents. Formal reports go to the corporate library, and they are available to all on-line. It is quite an effective system. The weak link, even today, is that not all technical people in the company know about the company's technical document protocol, and up to now, there was no text to explain types of technical documents and how to write them. That is the purpose of this book. We do not focus on the laws of the English language.This book discusses most types of documents that the average technical person will encounter in business, government, or industry. The overall objective of the book is frequent, effective, written documentation and the cost savings produced by effective communication.
