Structured What-If Technique (SWIFT)
Reference model
SWIFT helps visualize how changes in inputs affect outcomes, guiding better decision-making.
About this model
SWIFT is a structured approach to explore the effects of varying assumptions in decision-making processes, particularly in finance and risk management.
Originator not stated.
How to read it
- Start with the baseline scenario and identify key variables.
- Systematically vary each variable to see how it impacts the outcome.
What this does
Analyzes potential outcomes of decisions by systematically varying input assumptions to understand their impact on results.
When to use it
Use it when assessing risks and opportunities in financial forecasts or project plans, especially when uncertainty is high.
Not when: Do not use it when the relationships between variables are poorly understood or when the data is not reliable.
What happens next
Consider using a sensitivity analysis to refine the results further.
