Scenario analysis

Definition

Scenario analysis is a strategic planning method used to make informed decisions by evaluating different possible future events or situations. This approach helps identify potential risks and opportunities by examining various scenarios based on changes in variables or assumptions. It is essential for assessing how different conditions can impact system performance and for optimizing design and functionality.
