Purposedifferent | When teams derive needs only from assumptions and real motives are missing, user interviews give direct access to behavior and meaning. Conversations from the target group's everyday life make patterns, tensions, and open questions solidly visible. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. | The method protects energy and attention for the task that creates the largest progress and is often postponed. | For easily distracted solo work, the method sets clear time boundaries for concentrated work. It protects attention when large tasks would otherwise fall apart into small avoidance moves. |
