If you are designing and selling a product, you might have to write an Operating Manual. Your customers will need to know the product's features, maintenance information, and other general product descriptions. We've all read Operating Manuals at one time or another. Think about software manuals. Mechanical engineers write those, and may even write them for other engineers. For example, an engineer might write software that analyzes the stresses in a piping system and predicts the flow rate. Only an engineer can write the manual because it's very technical. It requires an understanding of how the software works.
