Purposedifferent | When a team juggles too many domains, systems, or handoffs, it measures mental overload as an organizational problem. It clarifies responsibility, interaction, and load between teams. The result is captured as a cognitive-load profile and action list. | For a single, hard-to-explain deviation, the method exposes the causal chain behind the visible symptom. It keeps the cause open until a controllable condition emerges instead of a mere description. | When a problem keeps recurring and the cause stays unclear, the method exposes the underlying mechanism. It separates symptom, guess, and robust explanation from one another. | For a risk that can only be managed through multiple layers of protection, the method examines the effectiveness of each barrier. It shows where safeguards are missing, too weak, or fail under real conditions. |
