DefinitionThe structured scenario method (構造化シナリオ法) is a design technique that divides user scenarios into the stages of value, activity and interaction, writes them in order from abstract to concrete, and applies them to design.
ExplanationA scenario (シナリオ) is a story-style description of what users do and for what purpose. The structured scenario method writes, in order, the value scenario (バリューシナリオ) describing the value provided, the activity scenario (アクティビティシナリオ) describing the actions that realize it, and the interaction scenario (インタラクションシナリオ) describing exchanges with screens and devices. Because each lower stage follows the value set at the stage above, operational details are less likely to drift away from users' goals.
AnalogyIt is like building a house: first you decide how the family wants to live, then picture how a day will go, and only then decide where the switches and shelves go.
Memory hookLine up the three scenarios as the questions "why (value) → what (actions) → how (operations)" and they are easy to remember.
