Follow one promise through three surfaces.

Choose an existing route: an image and page, a short introduction and longer explanation, or a demonstration and invitation. Three surfaces are enough to reveal a useful pattern.

For each, write one sentence describing what a newcomer would believe after encountering it. Use the newcomer's likely understanding, rather than what the creator intended to communicate.

Now compare the three sentences.

Look for a meaningful addition. The second surface should give the reader something the first could not carry as well: mechanism, proof, context, interaction, or a next possibility.

Look for a change in promise. Has the subject shifted? Does a word mean something different? Is the later invitation asking the reader to value something the journey has not explained?

Look for a missing route. Where would someone wanting more proof go? Where would someone already interested act? Can the person return from depth to the practical contribution?

Look for duplicated work. Are the picture and headline saying the same thing while leaving another important distinction unexplained? Does the long form merely repeat the short one?

The exercise is useful even when you do not immediately change anything. It can identify which relationship deserves attention before you invest in another asset.

Howard Pearlmutter's experience connects technical explanation, human interfaces, graphics, interactive models, and practical systems. A team session can examine an actual representation or journey with the relevant participants.

For examples, read the showroom, factory signoff, and the NASA human-interface story. For another level of explanation, explore one promise across surfaces.

Keep the useful addition. Repair the unintended change. Give the next question somewhere worthwhile to go.
