Figure 17. Example of sensitivity analysis with a tornado diagram. The tornado diagram has a central vertical axis from which bars extend left and right, their length corresponding to the influence of the factors they represent on risk. The bars are ordered so that they decrease in influence as they go down. The first five factors with the greatest impact on total cost variation include:

• Atlantic Locks excavation productivity
• Steel Prices for Rebar Locks
• Diesel Price
• Wage Increases for the Locks
• Formwork Productivity for the Pacific Locks
