|---|---|---|---|
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. | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. |
