This document discusses technical descriptions. It identifies the purpose of technical descriptions as providing additional details to help readers visualize what is being described, beyond just a definition. There are two main types of technical descriptions: product descriptions, which describe what an item is like, and process descriptions, which describe how something works. Elements of a good technical description include a clear and limiting title, appropriate level of detail for the audience, illustrative visuals, and an appropriate sequence such as spatial, functional, or chronological. The document also provides tips for writing objectively with precise photographic language.
