About Crystal Ball Simulations

After you define assumption, forecast, and decision variable cells in a spreadsheet model, you are ready to run a simulation. Then, you can analyze the results.

To run simulations in Crystal Ball, follow these basic steps:

  1. Define assumptions (Entering Assumptions), forecasts (Defining Forecasts), and decision variable cells if appropriate (Defining Decision Variable Cells).

  2. If you want, customize the appearance of each cell (Setting Cell Preferences).

  3. Set run preferences (Setting  Run Preferences).

  4. Optional: Exclude certain data cells from the simulation by “freezing” them (Freezing Crystal Ball Data Cells).

  5. Run the simulation (Running Simulations).
