Keep the drawing beside the words

A fictional opinion piece about assembly instructions. Original practice text.

The replacement instructions fit on one elegant page. The old version took four. It is tempting to call the new version simpler before anybody has tried to assemble the stool.

A reader can follow every sentence and still hold a part the wrong way round. “Attach the side rail” does not tell them whether the small hole faces inwards. The old drawing does. When an illustration carries information absent from the words, removing it has not removed complexity; it has handed that complexity to the person doing the work.

Pictures can mislead too. A beautifully shaded image may hide the joint it is meant to explain. An arrow can point so broadly that the reader cannot tell which edge matters. The case for illustration is therefore not a case for decoration. It is a case for deciding what each form can show clearly, then checking that the forms agree.

The best test is not whether a designer can explain the sheet while standing beside a colleague. It is whether someone unfamiliar with the object can use the sheet without the designer. Watch where that person turns a component over, looks back or begins again. Those movements are questions the page has failed to answer. Adding another confident sentence may not answer them either.

Before we celebrate a reduction from four pages to one, let us count the reader's extra guesses, not only the pages saved. Keep the drawing where it makes orientation visible. Keep the words where they name a condition a picture cannot establish. Good instructions do not require a loyalty oath to text or image. They require the two to stop leaving work for each other, and for the reader.

How does the writer persuade readers that illustrated assembly instructions should be retained? Support your response with evidence from the text.
