Effective scenario management tools need to meet these objectives:

• Minimize the number of model files the modeler needs to maintain (one, ideally).
• Maximize the usefulness of scenarios through easy access to things such as input and output data, and direct comparisons.
• Maximize the number of scenarios you can simulate by mixing and matching data from existing scenarios (data reuse)
• Minimize the amount of data that needs to be duplicated to consider conditions that have a lot in common

The scenario management feature in Bentley StormCAD successfully meets all of these objectives. A single model file enables you to generate an unlimited number of What If? conditions, edit only the data that needs to be changed, and quickly generate direct comparisons of input and results for desired scenarios.
