What it means
It bridges the gap between an appealing promise and the practical experience of using a product or service. The steps should describe meaningful actions or outcomes, not arbitrary divisions of a paragraph. Images can help when they show what changes at each stage.
Use it in practice
Use a consistent level of detail and make the sequence clear. Include any important commitment or prerequisite before the final call to action.
Watch out for
Do not force every process into three steps if that hides necessary information. Avoid repeating benefits without explaining the actual process.
