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. | Porter Five Forces analyzes the forces that shape competitive pressure and profitability in a market. The view of market structure goes beyond individual competitors and reveals systemic pressure points. | Value Chain Analysis shows where value is created, costs accrue, and differentiation becomes possible along the process. It compares strengths, risks, market logic, and courses of action. The result is captured as a value-chain map and lever list. | PESTLE Analysis makes political, economic, social, technological, legal, and environmental influences visible. The environment of an initiative is thereby read systematically instead of through isolated trends. |
