|---|---|---|---|---|
Purposedifferent | A Future Reality Tree shows how desired actions are meant to lead to a better system state. The method checks whether a path of change holds together logically before time flows into implementation. | The method makes visible why two seemingly incompatible demands arise and which assumption must be tested to resolve the conflict. | The method protects energy and attention for the task that creates the largest progress and is often postponed. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. |
