| Criterion |  Systems Thinking Stock and Flow Diagram |  Operations Barrier Analysis |
|---|---|---|
Purposedifferent | A Stock and Flow Diagram shows how stocks, inflows, and outflows shape a system over time. It is especially suited when growth, delays, or capacity limits determine the dynamics. | 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. |
