This book mainly presents strategies to write effectively in real world engineering/science situations, assuring that what you write is really read. It shows how to present your ideas so that your target audience understands it. It describes the characteristics that a document aimed to a technical person, to a lay person and to a manager should have. Besides, it shows how to write memos, letters, reports and even e-mails, explaining from the initial document outline, sentece/paragraph structure to the final polished form. I wish I had read this book when I was an undergrad, I had to learn how to write effectivelly.
