Technical object description for a non-technical audience

The whole assignment turns on the audience clause, and it is the clause students read last. A description written for someone who already knows the object is a specification; a description written for someone who does not is a translation. That difference changes almost every sentence you write. It rules out unglossed jargon, but more importantly it changes the order in which information has to arrive: a non-technical reader needs to know what the thing is for before they can absorb what it is made of, whereas a technical reader can take the components first and infer the purpose. If your description opens with dimensions and materials, you have written for the wrong reader however accurate the content is. Ask what the reader would need to already understand for your first paragraph to make sense, and if the answer is anything about the field, rewrite it.

The brief names three things to cover — looks, features and functions — and they are not synonyms, though drafts routinely collapse them into one. Looks is the physical description: shape, size, material, finish, the parts a reader could point at. Features are the deliberate design choices, the things somebody decided to include. Functions are what the object does and how the features enable it. Keeping the three separate is what produces a description rather than an impression, and the cleanest way to hold the distinction is to describe the whole first, then break it into parts, then say what each part does. That partition also gives you a natural structure, which matters because this assignment sits inside a document design unit, and the layout is being assessed alongside the prose rather than after it. Headings that mirror the three-part split do double duty here.

Choosing the object is a real decision and it is worth spending two minutes on. Something too simple gives you nothing to translate and the description becomes padding; something too complex forces you to skip the mechanism, which is the part the exercise exists to teach. The productive range is an object with roughly three to six identifiable parts whose interaction is not obvious from looking at it — a stethoscope, a pressure regulator, a mechanical keyboard switch, an infusion pump cassette. Test your draft the only way that works: give it to someone who does not know the object and ask them to describe it back. Whatever they cannot reconstruct is where your description assumed knowledge the reader did not have. That gap is the actual deliverable being marked, and no amount of careful proofreading will surface it the way one confused reader will.
