What-if analysis

Definition

What-if analysis is a method used to evaluate the potential outcomes of different scenarios by altering key variables in a model. This approach allows engineers and decision-makers to assess how changes in one or more factors can impact processes, safety, or efficiency, enabling better risk management and optimization strategies.
