|---|---|---|---|---|
Purposedifferent | In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected. | The VRIO Framework rates resources and capabilities on whether they are Valuable, Rare, Inimitable, and Organized. It compares strengths, risks, market logic, and courses of action. The result is captured as a VRIO table and strategic actions. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | A Business Model Stress Test checks how well a business model holds up under pressure and headwinds. It compares strengths, risks, market logic, and courses of action. The result is captured as a stress-test report and action plan per scenario. |
