Purposedifferent | A Current Reality Tree condenses many symptoms into a few causal chains. The method makes visible which core problems drive several negative effects at once. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. | The Iceberg Model separates visible events from patterns, structures, and mental models. This turns a single observation into a deeper understanding of why a problem keeps recurring. | The Theory of Constraints Thinking Process exposes a system's bottleneck and the logic behind it. It suits situations where many symptoms trace back to the same limiting relationship. |
