You're probably wondering what this "technical writing thing" is. Someone may even have told you, "It's this course where they make you write about rocket science and brain surgery." Well, not really, as you will see in a moment. Actually, the field of technical communication is essential in a wide range of fields and occupations. It is a fully professional field with degree programs, certifications, and—yes!—even theory. It's a good field with a lot of growth and income potential; and an introductory technical-writing course for which this book has been developed is a good way to start if you are interested in a career in this field. Technical writing is an audience-centered means of communication that provides a reader with clear and easy access to information. In the business world, time equates to profit, and profit is the force behind all business interaction. The technical writer and reader have a vis-à-vis relationship. The writer recognizes, respects, and addresses the importance of time in effective and efficient communication by providing documents written in specific formats, using unambiguous language to send clearly accessible information. The reader in turn thoroughly understands the information in order to give a thoughtful response.
