Step-by-Step Procedures

Use step-by-step procedures when describing tasks that the reader must carry out in a specific order. Never bury procedures in narrative form. Use step-by-step when there is a consistent linear pattern without a lot of decisions to make. If there are a lot of decisions to make, consider using a decision tree instead.

Follow these guidelines when writing step-by-step procedures:

• Use the imperative style, beginning each step with an action verb (for example, “Calculate the amount of tax payable….”).

• If the step is conditional upon something else, state the condition first (for example, “If you have expenses, complete the Expense Form and attach your receipts.”).

• Order steps in the sequence in which they must be carried out.

• Number each step. Don’t include more than one activity in a step.

• Leave a space between each step.
