When writing step-by-step instructions, what is the most important principle to follow?

Question

Accepted Answer

Present steps in chronological order, with each step describing a single action. The most important principle for writing step-by-step instructions is to present the steps in chronological order, with each step describing a single, discrete action. This one-action-per-step approach prevents confusion, reduces errors, and allows readers to complete each action fully before moving to the next. Steps should begin with an imperative verb (click, open, insert, tighten) and be numbered to indicate sequence. This clear, sequential structure is essential for safety-critical procedures and for users who may be unfamiliar with the process.

Including as many steps as possible in the name of thoroughness can overwhelm readers with unnecessary detail and obscure the essential actions - good instructions include exactly the information needed, no more. Using complex vocabulary to demonstrate expertise contradicts the goal of clear communication; instructions should use the simplest language that accurately conveys the required action, matching the audience's technical vocabulary. Combining multiple actions into a single step to reduce step count creates ambiguity and increases the likelihood of errors, as readers may miss one of the combined actions or perform them in the wrong order.

Writing effective instructions is one of the core skills tested on the Technical Writing DSST exam. Students should understand the conventions of instructional writing including numbered steps, imperative mood, one action per step, visual aids placement, and the inclusion of warnings and cautions before the steps to which they apply. User testing of instructions through protocols like think-aloud testing is also an important related concept.
