|---|---|---|---|---|
Purposedifferent | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | When systems fail unexpectedly, spontaneous attempts often produce more noise than insight. Hypothesis-driven Troubleshooting translates symptoms into testable assumptions and makes troubleshooting learnable. | 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. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. |
