This document discusses technical descriptions. It defines technical descriptions as providing additional details to help visualize what is being described, like definitions. There are two main types: product descriptions, which describe what an item is like, and process descriptions, which describe how something works. Good descriptions have a clear title, appropriate level of detail, illustrative visuals, and a logical sequence. They should use precise, photographic language to help readers visualize the item objectively.
