Simulation Runner

The Simulation Runner is a powerful environment for What-If Analysis. It allows you to modify your decision logic safely and test it against real-world data to forecast outcomes.

What-If Analysis​

In the Playground, you are working with a detached copy of your model.

  • Modify Logic: You can change decision tables, literal expressions, and dependencies to test new hypotheses.
  • Safe Experimentation: Changes made here do not affect the saved version of your model until you explicitly choose to export or save them.

Running Simulations​

You can execute your modified model in two ways:

1. Manual Inputs​

Manually define test cases to verify specific scenarios or edge cases.

2. Historical Data​

Re-run your decision logic against past executions.

  • Select a timeframe.
  • The runner replays this data through your modified logic.
  • This allows you to see how your new rules would have performed in the past ("Backtesting").

Analyzing Results​

Output diff​

Compare the New Output (from your modified logic) against the Original Output (if available) to verify correctness.

KPI Impact​

Observe how your changes affect key business metrics.

  • Pass/Fail Rates: Did approval rates go up or down?
  • Risk Distribution: specific outcomes frequency.
